My most active games at the moment are Final Fantasy III on DS and Rallisport Challenge 2 for the (original) Xbox.
I'm having a lot of fun playing FFIII. The DS re-make graphics are great, and I love the job system. FFIII is where the Final Fantasy series really starts to come together in a good way, in my opinion. I'm having a lot more fun with it than I did with FF or FFII. It really shows you where they got the inspiration for Final Fantasy Tactics. Sometimes I wish they'd made the job/skill system in FFIII more like they did with Tactics later on, for instance, you can't use a previous job skill during the time that you specialize in another job, as opposed to being able to put a previous job skill set in your secondary skill slot in Tactics. However, once you earn the job levels for a particular job, you don't lose them if you change, and you can change back to a previous job relatively easily with no permanent penalty.
Rallisport Challenge 2 has been my first serious foray into rally racing. I've never been good at racing games (or any type of game, really), and I'm far from being an expert, but it's a lot of fun, but not just that. Rallisport Challenge 2 is a truly beautiful game with awesome scenery, just the right amount of great jumps, great camera angles for power slides, and is delightfully accessible right at the beginning without sacrificing challenge in the latter races. I think I may have really found a gaming niche for myself, if I can stick with it, not because I'm all that great at it right now, but because it's a competitive, widely played game type that I really enjoy playing, for a change.
