Dunno if I can call it the best ever, but my time with the system has only really begun recently. Currently playing Napple Tale with English patch and I really love the Klonoa + Studio Ghibli + Nadia style vibes of that game so far. It's a 2.5D platformer but they've clearly put a lot into the world-building and there's a lot of dialog even at the start, feels like a JRPG in that sense.
One of the only other games I've put some time into is Karous; excellent soundtrack there. Like I said, I need time with more games and some of the best games got ported to other systems just a few years later (Sonic Adventure, Crazy Taxi 1 & 2, Rez etc.), but I would definitely say it's within my Top 10 without a doubt.
Indeed both systems have better catalogs
Everything I hate about modern gaming started with the Dreamcast
Everything I loved about gaming died with the Genesis/Saturn
You'll have to explain this, because I can't picture anything Dreamcast did outside of (for the time) biggest push for online gaming, that MegaDrive and Saturn didn't already do. Style-wise Sega's 1P stayed generally the same if not got even weirder with some games (Seaman, Segagaga etc.). It had a lot of fighters just like Saturn, ample amount of shmups (also like Saturn, and MegaDrive), arguably more 3P support than Saturn (kinda iffy; it definitely had more Western 3P support than Saturn, but maybe less Japanese 3P support), great marketing campaign etc.
It's one thing if MegaDrive & Saturn are better in your eyes but pinning all of modern gaming's problems on Dreamcast truly makes no sense. Dreamcast was really the last console IMO that represented the Old Era of gaming, with some ideas to bridge it to the New Era. If you want to actually pin where some of modern gaming's more questionable stuff started you should probably look to PS2, OG Xbox or Gamecube tho IMO even those are kind of a stretch.
A lot of modern gaming's more persistent issues, I think the majority would agree, really started to begin with 360/PS3/Wii generation, well after Dreamcast.
They tell you how great the Dreamcast and low and behold Sega rolled over to Sony Microsoft and Nintendo. In console worlds you have to be really to last generations.
There are exclusives on Sega consoles I enjoy more than most exclusives on any Sony, Nintendo, or Microsoft console. When people talk about how great these systems are, it's usually because of the games, not how many units the console sold or if the platform holder is still around.
Another reason they talk about how great these systems are is because of the culture they fostered. There's just a certain vibe/atmosphere to Genesis, Saturn, Dreamcast, Neo-Geo, PC-Engine etc. that you won't get on other platforms from Sony, Microsoft, Nintendo etc. Having that variety is a great thing in the industry especially for gamers who play on more than one platform.
Capcom will always get a bye from me following their support for the Dreamcast.
It was years ago, a senior figure was interviewed by either the Official UK DC magazine or DC:UK and stated that "Capcom is determined that the Dreamcast will succeed, even if we have to do it ourselves"
'90s Capcom is so interesting because by the mid-90s it almost felt like there were two sides of the company; the old-school side that grew up with arcades and arcade-style games, and the new emerging side that was pushing for more story-driven, single-player polygonal experiences. It's very clear the former grew a very close bond with Sega and went that direction, while the latter ended up preferring Sony.
That said, games of both types would come to both platforms, but Dreamcast provided an opportunity for Capcom to get a cost-effective arcade platform (NAOMI) and a home console that'd allow for effortless porting (Dreamcast); remember by the late '90s their arcade side was hurting due to the failure of the CPS3 and Capcom wanted to jump ship immediately. NAOMI presented the perfect opportunity in terms of being great at 3D AND 2D graphics, so it worked out great for them and Sega.
