What is a good RPG to play for sessions of 2 hours or less?
That's kind of a trick question. Because almost any RPG can be played in 2-hour sessions (although I would not recommend Chivalry and Sorcery* with combat in it, that takes at least 4-6 hours). If you mean, as part of an ongoing campaign at least.
If you mean as a one-shot or as a picaresque game? That's different. And does that 2-hour include character generation or pre-generated characters?
If you have a one or two scene adventure, most games can be played in 2 hour sessions. Games I have played in short sessions include Indiana Jones, Ironclaw, and Feng Shui. But even Pathfinder, a game some consider rules heavy, can have a 2-hour game session, if you use pre-gen characters and a one or two scene adventure. Feng Shui on the other hand, you can do character generation and an adventure in 2 hours. Even with gaming novices. Fate is the same. You can get started with partially created characters and finish them in the game.
*Chivalry & Sorcery has a great setting, and it's a good game. But the combat is a bit complex. Or at least, that was the case for the edition we were playing.
