Hmm. Most of the replies thus far seem kind of generic. I would list my requirements in order of importance, like so:
1. Story.
2. Aesthetic appeal. This includes everything from graphics to music to voice acting. I don't care if the graphics are cutting-edge as long as they look beautiful. Some of the older games I have (Gothic, Drakan) are STILL MORE BEAUTIFUL than newer games with better graphics.
3. Interesting challenges. This can come from fights or puzzles or what-have-you. Being *difficult* is not the same thing as being *interesting*. Variety is the spice of life. Ideally you want the game to constantly engage you in the process of trying to outsmart it (even if this isn't terribly hard) so you have a sense of accomplishment.
4. A sense of freedom. I like "open world" games for this reason. It can be rewarding just to have the ability to get out and wander around in an interesting environment. It also makes games where you can "break" quests by doing things "in the wrong order" (or similar problems) extremely painful to play.
I see gear and the character leveling system (assuming there is one) as a means to an end, not an end in themselves, so I can take or leave them.
Yatzhee actually mentioned something that I have been harping about for years. I'd like to see RPG's where the entire experience is integrated. That means, for instance, that the "game mechanics" are actually treated like the "physics" of the game and are taken into account. In an integrated game, you'd never be sitting with a scroll of resurrection while a party member dies dramatically a la NwN2. The "side quests" and "main plot" should also tie together in some way so that you're never doing some stupidly artificial thing like neglecting to save the world so that you can go fetch a dozen boopstickles for some helpless yahoo.
If you're looking to create an immersive world, the first thing you have to do is to hide the seams.
