Nobody really had a Saturn and for the most part it is mostly only known today to people that know the games (Saturn Bomberman had a reasonable case for being the best, definitely top 5 though, and that alone tips the scales massively for many) or have explored it afterwards, and given the price and general lack of them in cheap and easy second hand markets more than 5 minutes after it cratered (I live in the UK, the megadrive was huge here and probably bigger than the SNES throughout most of it, and been buying second hand games since the 80s... never seen any kind of abundance of Saturn games outside of game shops shifting their stock at the end. Travelled the US in similar timeframes doing the same and nope.). Even then with the games being CD iso size and emulation trickier than some might like it does rather preclude you from exploring things like you might the 16 bit and older stuff or handhelds where it is open and go after downloading a few dozen megs at best of ROM.
The Dreamcast however had something like a bit more success and awareness at first, and has since gone on to host some of the best examples of games from its weird halfway between the generations thing. Plus those people with no taste that think Sonic Adventure is not an abomination -- I learned never to discount those in this sort of discussion.
I guess I'm one with no taste lol.
I played through Sonic Adventure 1 again recently, and I still enjoyed it. I won't say its a masterpiece, or a perfect game, or even close.
But I did have fun with it. And the way they transformed 2d to 3d creating its own world was no Super Mario 64, but boy oh boy were those graphics jaw dropping at the time. One could argue that's what made Dreamcast feel significant at the time in the late 90's/early 00's. It really felt like a dream... cast.
I have yet to play through more than the beginning parts of SA2, but I plan to sometime as well.
I have SA1+2 on GameCube too just as collectors sets, but I've heard they're god awful ports so I never really gave it a proper run down. I might just for SA2 battle being slightly different, but not really any interest in SA1 on Gamecube after watching some Youtube videos breaking that one down
