Alright, now I'm gettin some ideas!
To answer a few people and give some more info:
EVERYTHING I've heard about Fable III has warned me to stay away from it, especially the clunky battle system. Maybe later, but def not now for $60.
I already own Diamond and Soul Silver, forgot to mention them.
Have been considering Dragon Age and Elder Scrolls IV, so I'm glad to see some people recommend those.
Reasons I disliked Fallout 3 and Chrono Trigger:
Fallout 3 was fun for a while, but I really hated how you were almost forced to rely on the VATS, and for me if felt like it hardly ever came through. The standard battle system just wasn't crisp enough to rely too much on FPS skills. (Unless I missed something.)
I really can't say what turned me off about Chrono Trigger, but my suspicion is that it has something to do with never playing the original. It just seemed to plod along to me, and the battle system just wasn't intriguing. (Even though it's quite similar to some RPG's that I love.)
The two games I'm most on the fence about are Mario and Luigi: Bowser's Inside Story and Tales of Vesperia. They just don't look like my normal cup of tea, but I've read glowing reviews on here and other sites. I'm ALMOST over the edge to where I'm considering asking for them. Almost, so feel free to give me a push.
I have heard horror stories of the grinding in Disgaea, so that's kind of a turn off.
For a good part of today I will be going through all the recommendations that have been made, thanks to everyone who has replied, but please keep them coming if you can!
