I just bought a Dreamcast that didn’t read discs, and am about to install a gd emu that just arrived in the mail. I already have an sd card with every US released game(I am located in US), and I think at least a couple Japanese English fan translations, I haven’t been able to see what yet. Also some atomisware stuff. I am just curious, I’ve never had a Dreamcast before as I grew up on Nintendo, what are some games that I absolutely have to check out first? What games made the Dreamcast shine? I have such a large selection that it would be super helpful to have some suggestions from you guys!
