Sega Dreamcast isn't state-of-the-art anymore, but this was the foundation of our modern game consoles. It introduced complex online gaming. It showed what a 3D game could really look like. And, most important of all, it was fun and creative. Although it lasted less then a year (thanks to stupid ugly Sony and their clunky uncreative Playstation 2) in North America, it got a lot of crazy games onto the market. Sonic Adventure is a great game that set the base of who Sonic would be in the modern era. Yet this time Sega didn't stop at Sonic. Crazy Taxi, Jet Grind Radio, Chu Chu Rocket, and a ton of sports games and RPGs all made the Dreamcast the place for creativity. Not only that, Dreamcast introduced the VMU, a Gameboy-style memory card with a monochrome screen that displayed game information and occasionally even let you play games on it.
