I am saying that the 3d schlock is what made the console or Playstation. A game like Symphony of the Night was nice but it was niche, and I don't think it sold that well on the Playstation, maybe in Europe because I have seen copies of another castlevania game on Playstation.
the big PS1 games where FF7(any of the 3d FF games was a big to a huge deal), MGS, Resident Evil, Tomb Raider, Crash Bandicot, Spyro, Tekken 3, Gran Turismo and Ridge Racer, wipeout, Silent Hill.
There are obviously more games that was huge but these are what I remember was the big talked about games.
You obviously have allot more remembered games, the PS1 library was huge and there was allot of games on PS1.
So the dreamcast even if would've gotten a MGS or Crash, or FF9 then people would've asked why buy that when I have it on PS1?
I know you don't believe me, when I say this but Tomb Raidre was huge, like really big deal of a game. And allot of the games are on the dreamcast but no one cared, even Tony Hawk (I think) is on the dreamcast. So it had the big name IP's.
So, it is the outsider/only being sold at selected markets and some bad 3rd party support(mostly Japan only support), along with being released too early.
I don't think you can blame the Saturn on the failure of the dreamcast, also some of the 3rd party that didn't support the dreamcast didn't do it because the hardware or CPU and I think the GPU was too exotic and out there.
