FFXii reveant wing if you like snes rpgs and rts games
the two Castlevania i prefer the first
If you have friends with a ds need metroid prime hunter and a bomberman for multi
If you like srpg buy luminus arc it´s very good with voice and anime desing
And the best for me hotel dusk for me the best adventure of point and click
Other than is good it´s eragon game it´s a mini zelda ocarine of time
Wait that this list help you i try give different types of game for you choice
