Dreamcast takes it all the way. I would encourage people to read Dreamcastjunkyard's top 200 DC games article. The system is overflowing with unique and amazing games.
Xbox was great for its own exclusive games for sure, but DC just had more and better exclusives that were made specifically for it.

Dreamcast and Genesis games are still being made to this day. OG Xbox on the other hand is basically a dead system.
