I was able to play it a bit at a retro gaming museum. I really didn't think it was as bad as its reputation suggested. The controls were a bit awkward but usable, and the load times weren't that long for a console.
I'm an odd one out, my all time favorite was probably that racing game Rush 2049. My brother and I put insane hours in. My parents (mostly my mom) were super against video games, thought Pokemon were satanic, any violence would turn our brain to mush, etc... So when we were initially reluctantly given a Dreamcast (after it had already had its run, my mom bought it on clearance at Sears after it was discontinued), we only got "wholesome" games (that my mom could find in the clearance bin) like a surfing game, tennis game, Xtreme sports, and some racing games. Somehow Toy Commander snuck in there with its "violence", but I guess it was ok because it was cute and squishy.
I'd say the top 3 are Rush 2049, Toy Commander, and Vigilante 8 (We eventually bought some games for ourselves with our own money and our own rules, and Vigilante 8 was one that we played a ton. My dad was a big fan of that one, and thought my mom's over zealousness was silly so he "let" us keep it, as long as we let him play too lol)
I never had any of the crazy popular games listed here like Powerstone, Skies of Arcadia, Soul Caliber, etc, but we enjoyed the SHIT out of that Dreamcast. Still have it, I've replaced the dead GDRom drive with a GDemu, and a new modern power supply, and it works great.
When ever I think of this game I think about the synchronised swimmer guy, I can still see that special move where there are like 5 of him twirling around the opponent. They don't make shit like they used to xD
