I prefer classic games to modern games though I do play them ALL. My favorite games being shooters -- real shooters like Gradius, R-Type, Raiden, et cetera…
For XBLA, I got a few game:
Space Giraffe
Omega Five
Lumines Live
Every Extended Extra Extream
Castlevania Symphony of the Night
many others.
I get alot of fun playing these games and some of them are great and well worth their price. Omega Five is top notch and well worth 800pts ($10)! Some games are average and have their problems though. Contra is good but 2 player (online) is so broken. Super Contra has less problem with 2 player but then the game is not as good.
My biggest problem is that the d+pad on the 360 controller is absolute rubbish. I have no choice but to use my arcade stick but some games do not offer button remapping
So yeah, I like XBLA and look forward for more cool games to come. Currently I am waiting for Ikaruga, Trigger Heart Exelica, and Rez. I guess Trigger Heart and Ikaruga are already on partner.net so hopefully they will be on within the next 6 months…
