My personal choice is of course bias, but I'm totally going for the Dreamcast. It was between it and SNES. The Dreamcast was definitely ahead of it's time with some of the most enjoyable games to date. A lot of them were exclusive to the Dreamcast. The games, online, VMU, etc. I absolutely adore it. I know I'm in the minority, but I just loved it. Still do and mines is in pristine condition along with my games. Not a scratch on them. SNES was everything and more. I could list a million reasons why it should be #1, but I would spend too much time trying to narrow down thee best reason.
