Definitely the first Sonic on the Genesis. I play the ROM of it on my PS3 because I hacked into the console and installed the Genesis emulator on it, so I play it on 32' HD xD
My fave Pokemon games are Platinum and SoulSilver! I liked Black, but the only bad thing is the lack of extra things to do after the main story. Usually, i'm always playing either Platinum or SoulSilver. My fave Pokemon characters are Hilda and the B2 & W2 female protag. Both alongside Sonic the Hedgehog are my no. 1 fave game characters =D! What is your fave Sonic game?
