Welcome to the Generic Universal RolePlaying System!
With GURPS, you can be anyone you want – an elf hero fighting for the forces of good, a shadowy femme fatale on a deep-cover mission, a futuristic swashbuckler carving up foes with a force sword in his hand and a beautiful woman by his side . . . or literally anything else! Thanks to its flexibility, quality writing, and ease of use, GURPS has been the premiere universal roleplaying game for over three decades!
A Very Different Approach to the "PbtA" Games [ edit ]
In many respects, GURPS sits on opposite ends of the spectrum from games like Legend of the Elements and Fellowship. While LoE was made for Avatar, GURPS (the Generic Universal Role-Playing System) was instead made to support any setting. While LoE (and its PbtA-core) is extremely rules-light and story-heavy, GURPS instead provides extremely detailed ("crunchy") rules. And while both PbtA systems are relatively new, is now on its fourth major edition, having originally been released in 1986.
Instead of simply picking a class and a few details, GURPS characters are built by using points to buy all of their individual details, such as stats and skills. This system allows virtually any character to be created, not just a particular class or "playbook" ... but it does mean that character creation is slower than in LoE.
Also, GURPS character creation is purely mechanical and focused on the character. There are no background story or campaign world development parts, as there are in PbtA games.

Character Creation [ edit ]
Character creation in GURPS is detailed, but slow. There are no levels or classes, just points, which can be used to buy attributes, advantages, disadvantages, or skills. Different campaigns start with different amounts of points, so that (for instance) a superhero can start out as a more powerful character.
GURPS has four attributes: Strength, Dexterity, Intelligence and Health. Strenght and Healthy just define the character physically, while Intelligence and Dexterity are combined with skills to make skill checks.
Skills are how characters accomplish things in GURPS; for instance to shoot someone you would use the "Guns" skill. Skills are based on attributes, so for instance you might buy the Guns skill at a "Dex + 1" level. If you later improved your Dexterity, you'd similar improve your ability to shoot ... or do anything else physical.
Advantages cover any non-skill benefit a character might have, such as a high pain threshold, wizard training, or the ability to move objects with their mind. Advantages can also be further be customized with enhancements or limitations, allowing you to gain more or less powerful versions, that cost more or less points as a result. This can allow for a nearly any power you can imagine to be described as a GURPS advantage.
Similarly players can also take disadvantages for their character, such as Code of Honor or Blind, to gain extra points. All together this system allows for incredibly individualized character, including almost any you'd want to re-create from fiction or real-life (in fact, there are multiple GURPS books with stats for historical NPCs such as Ghengis Khan) ... but it can be a bit overwhelming to newcomers.
Core Mechanics [ edit ]
To succeed at an action in GURPS, players roll 3d6 and attempt to rull under a target number, which varies depending on the action. Most of the time the actio will be a "skill check", meaning the player will have to rul equal to or less than the character's relevant skill.
Critical Successes and Failures
If you fail a roll by more than 10 you critically fail the roll, and the GM decides what terrible fate results. Similarly if you beat the roll by more than 10 you instead get a critical success, dealing extra damage or otherwise succeeding with flair.
A Note About 3d6 (vs. d20 or Other Dice)
3d6 results in a far more predictable distribution of rolls than a single die roll (typical in other systems). Think about when you roll stats for a Dungeons and Dragons character: you usually get a lot of more 10's and 11s than 3's and 18's. In contrast, every d20 roll has an equal (5%) chance of rolling a 1 or 20 as it does a 10 or 11.
This allows GURPS to have critical successes and failures, but have them be rarer and more dramatic, while leaving most rolls with fairly predictable/average outcomes.
Combat [ edit ]
GURPS uses a hexagonal grid for combat. Hexes offers a benefit vs. square grids, when it comes to diagonal movemen: in square grid games (eg. D&D) characters moving diagonally move more quickly ... but since hexes don't have corners, they don't have this problem.
Unlike most games, GURPS does not have a random element to initiative. Instead, characters always move in order based on their basic speed (a stat derived from their Dexterity and Health scores).
If one group surprises the other they can potentially get several seconds of actions before their opponent can react ... and since a single round of combat in GURPS lasts a second, that can be significant.
On their (one second) turn a a character can take a single maneuver, plus any number of free actions (eg. talk or drop an item). A maneuver could be to move, attack, or move and attack (at a penalty), as well as other options such as aiming or feinting. A character who moves can move a number of yards equal to their basic move (ie. basic speed with fractions rounded off).
To attack a character makes a skill check with the appropriate weapon skill, applying a variety of modifiers for things like the target's size, range, and speed, or the weapon's accuracy bonus (if they took the time to aim), the lighting conditions, any cover the target has, etc.
If the check succeeds the target can then opt to make an "active defense". There are three options: Dodge, Block (eg. with a shield) and Parry (with a weapon), and ranged attacks can only be dodged. Active defenses are also a skill check, for Block and Parry; to Dodge you simply roll your Basic Move + 3.
If the active defense roll succeeds, the attack misses.
If an attack roll succeeds the attacker gets to make a damage roll, which will vary based on the weapon they use and other factors (eg. ranged weapons do half their damage when far enough away from a target). If the defender is wearing any armor they can subtract it's "DR" (damage resistance) from the damage, and the rest goes through.
Depending on the type of damage dealt, it might be multiplied now (eg. cutting weapons deal 1.5x ).
Avatar in GURPS [ edit ]
Because GURPS is designed for any campaign you can imagine, it can easily be used to run an Avatar campaign. And in fact there are already a number of fans who have, and who've discussed their experience.
There's a great discussion of the topic here, and another here (both on the official forum of Steve Jackson Games, the maker of GURPS). But perhaps the best resource is this thread, where user Naloth has essentially written out an etire miniature GURPS supplement for Avatar in the thread. His rules are for GURPS 3rd edition, but because the two editions were similar these rules could easily be adapted to its current (4th) edition.
Should You Pick GURPS for Your Avatar Campaign? [ edit ]
GURPS is not in any way designed for Avatar: it has no official supplements, only unofficial, player-made material from fans. It also offers less story-driven, and slower/rules-heavier gameplay.
However story-driven and rules-light games aren't for everyone. If you are the type of gamer who wants more detailed and realistic combat mechanics ... instead of just a single "Commit Open Violence" move with a fixed difficulty ... a game like GURPS might be much closer to what you're looking for.
GURPS also offers greater character flexibility (with no pre-set classes/playbooks), better balance between characters, and its rules can be used to support virtually any other campaign you may wish to run: not just Avatar.
If you're looking for a well-established and popular system (though not quite as popular as Apocalypse World), with very detailed rules, GURPS Fourth Edition is another great way to experience Avatar ... or any other genre of adventure.
