If you are a Sony fan, don't bother reading this, as this post is about good games.
Yes, I am a devout, hardcore, whatever, Nintendo fan. I don't actually have an awful lot of games, but I'd like to say that I'm pretty decent at the ones I like: Super Smash Bros. Melee and Kirby Air Ride (only City Trial though) on GameCube, Pokémon Sapphire, Pokémon Pinball and Mario Party Advance on GBA and Mario Kart DS on DS. I will go through my 'favourites' on each of the above games. If you need tips on any of them, just comment on this blog.
