Videogames are like anything else you buy, if you're satisfied, you'll stay loyal to that company. If you order Domino's and they always deliver fast and it tastes good, you'll keep ordering Domino's, why take your chance with Pizza Hut? I've never been let down by Nintendo, NES, GB, GBC, SNES, N64, GBA, DS, GC; so why not be loyal to them?
