Well I don't know if your 360 is back yet from reading that but I am guessing it is:
I'd recommend
#1: Jade Empire (if you haven't played it) it can be DLed from the X-box originals section of the marketplace. It can also be obtained for the PC. Oldie, but goodie.
#2: Sacred 2, which was just released for the 360 (and has been out for the PC for a while). The story is a mixed bag to be honest, the voice acting is well... pretty aweful. But it's a decent action RPG. It's like an open world version of Diablo 2 with a lot of minor WoW style quests. The character customization is decent.
#3: Lost Odyssey, this one is Xbox360 exclusive but when it comes to storyline this is probably the best game out there for current gen, your basic JRPG in the spirit of Final Fantasy involving an immortal protaganist, who of course like most RPG protaganists has amnesia. Some very good writing, especially the stories that represent him getting his memories back. HOWEVER brace yourself for emo-overload.
#4: Saint's Row 2 is pretty epic, I enjoyed it far more than GTA IV. However be warned, you definatly play as an over the top bad guy. No good or evil choices here, your pretty much bad, bad, bad.
#5: *IF* you like survival horror that tends towards monster bashing, I also recommend Dead Space and Silent Hill: Homecoming. Both are pretty decent for the type of games they are (but fairly linear). Both have pretty decent storylines. The one in Dead Space is a lot deeper than you might think, especially if you check out connected sites like "No Known Survivors".
#6: *IF* your into super heroes, Marvel: Ultimate Alliance (very old by now) is also a pretty decent, if linear, RPG experience.
#7: If you like fairly old school RPGs, I whole heartedly recommend a PC game called Drakensang: The Dark Eye. That game has a deeply developed world and a very decent storyline. It's party based (recruit people to join you) though you get to create your own character to be the hero. The character development system is also a very deep one, including for the people you recruit. This is the best "true CRPG" in the last 5-6 years easily.
But basically, if your looking for a gaming fix and haven't done it yet I recommend Jade Empire. Cheap, availible for the PC (if that's what your using) and still stands up as an awesome game.
