for me, i bought my own Wii the day after my birthday, bought my own present.
I bought it for reasons being 1) MAINLY for SSBB 2) for my older siblings n parents can play the Wii without having a negative feeling about playing video games seeing that its ok to play video games 3) to have better connection with my few friends who also enjoy playing video games 4 because Nintendo has interesting games n icons ive played back in the NES days n ive never left them 5) n last but not least, because of the exclusive games that CANNOT be on PC.
now i know i was off topic, but my point is i only see getting a console for exclusive titles n fun for me n others to enjoy. If it's ever going to be about graphics, then its PC for me.
if i were u, get an Xbox 360. Though it's not 100% backwards compatible with all Xbox games, but u can also enjoy Xbox n now next-gen console games fro the Xbox 360 now or in the future, FYI Halo 3 that every Xbox 360 hardcore fan bought the Xbox 360 mainly for.
for RPGs, im not so sure about that because i prefer RPGs for PC i.e diablo 2, Hellgate: London, but i all i can say is look to see what is the best reviews, commented, n rated RPG title for Xbox or Xbox 360, see if the Xbox game is compatible with Xbox 360, or wait for future RPG games for Xbox 360 in the future.
......whew......i said Xbox 360 too much, lol sry about that.
