The realest answer. Also, I'd add that much of the Dreamcast's library consisted of ports of arcade games, with percieved short-term replay value. It was devastatingly light on adventure-style games you could sink your teeth into, the kind of experiences PS2 would be swamped with from day one.
100%
I had bought a Genesis 2 years after SNES, I enjoyed a lot on it.
Then bought into the 32X, which had.. nothing! I owned:
Star Wars Arcade - Average at best on a good day
Doom - in name only. PC blew it away
Knuckles Chaotix - where is 32 bit? It looked alright, but wasn't even fun compared to Sonic 3 & Knuckles
Virtua Fighter - fun for a few months
Virtua Racing - fun for a couple weeks
The music was still mostly farty FM synthesis, barely improved voice samples, and no games really had a vibrant color palette. The rest of the library was barely upgraded 16 bit shovelware.
Still, I bought into the Saturn hype and got it at launch:
Panzer Dragoon - really cool for a few weeks
Dayona - really fun for a few weeks
Virtua Fighter - fun again for a few weeks
Astal - ok it looks nice but what a snore fest
Dark Savior - ZZZZZzzzzz
It certainly didn't help that magazines at the time were hyping Saturn up so much.
From Gamefan August 1995:
"Astal is a visual force. These are easily the best visuals ever to grace a video game." 95
"The second best Saturn game so far behind Panzer is Astal." 94
"In the graphics department this game has no peers" 97
Uh ok yeah sure guys. What a snooze fest!
Ended up getting Sega Rally, Virtua Fighter 2, Panzer Dragoon Zwei and Saga, Nights into Dreams, Guardian Heroes, a whole bunch of import Capcom fighting games with the 4MB RAM cart. And yeah these were all terrific but talk about slim pickings.
It certainly didn't help that only AM2 was able to make the 3d graphics shine.
Sega Rally and Virtua Fighter 2 looked amazing, the high res mode that Virtua Fighter 2 used was gorgeous, but otherwise most 3d games looked and moved like hot ass. Actually I wish they looked like hot ass, then I might have been impressed lmao.
I'm sure I'm forgetting some games that I really enjoyed, but in all honesty, besides some of the arcade ports
I felt REALLY burned by Sega after all this. The few good single player games were very short. Within a few short years it felt like throwing over $1000 into a bonfire.
And once I got a Playstation 1 with that incredible library of games that only continued to get better, I never bothered to look at Sega again.
And frankly, I didn't miss much because Sega ended up doing pretty much exactly the same thing with Dreamcast. Really snazzy arcade ports, very light on content, no meat on its bones, very little to play long term.
