Sega's time making CD games. The kinda thing most gamers want to forget. I borrowed a Sega CD off a friend, lending him my SNES in return, for a few weeks. Suffice to say, I got the worse end of the deal. Sonic CD is okay. Not as good as the original sonic trilogy, and not as bad as some of the Sonic-based crap Sega churns out these days. It was decent enough.
Pokemon Blue and Red, however, defines the childhood of millions, mine included. The amount of time spent battling and trading. Playing outside with our Gameboy link cables rather than staying inside. I have nothing but good memories of Pokemon. I still remember my unbeatable team... Man, Gyarados was such a badass....
Ahem, anyway, yes. Pokemon all the way.
