If you disliked Quake Live because how limited it was. Then get Quake III Arena!
The main competitor to Unreal Tournament '99. This game is moddable, and you could find hundreds of custom models to play as, like Vash the Stampede, Darth Vader, and so many pop culture characters to find, download, and play as in Quake III Arena. Even you can download hundreds and hundreds of custom maps to play with others!
Regardless of the complaints being multiplayer-focused, it is still super fun, jump, run n' gun fun! Even id Software was nice enough to give us a single player game to get to the top in the campaign. Also, if you want to hone your multiplayer skills, bot match that is easy to find unlike Quake Live. Also, the Multiplayer is still alive to this day, knowing that people prefer this game over Quake Live.
If you were disappointed with Quake live, then get this!
P.S. You can actually see people's models unlike Quake Live! And it's also completely Buy-2-Play without having to pay for some silly premium content. Just buy and have fun.
