I was a Sega kid. Loved the Mega Drive. The Saturn is still my favourite console -- it was insanely underrated then and with limitations on porting it's even more obscure now. But it was the games rather than the consoles where Sega excelled. Unlike Nintendo or even Playstation, I never remember their console innovations being much to write home about and even quite interesting ideas like lock-on cartridges and VGU were met with anywhere from indifference to derision. Even at the time, the 32X seemed mad.
It's not so much that they lost their console division but that all their game development talent seemed to drain away and they let some amazing series drift into obscurity.
Sonic Team seemed to crash and burn hard. S3&K and NiGHTS are two of the greatest games ever made but then as I recall the team split into about four groups. They just about held it together for a bit with flawed-but-fun games like Burning Rangers, Chu Chu Rocket and the original Sonic Adventure but things went downhill fast. I thought SA2 was a shambles and that's remembered as one of the better games; the shambolic new NiGHTS was the most hurtful given how magical and perfect the first one was. Mania is the only Sonic this century of any note and it's made by fans and 70% remixes of old stages.
Then there's the loss of Camelot. The Camelot Shining Force games are peerless but SFIII never even made it fully to the west. Time was, Camelot would come up with a new twist on the RPG every year - Zelda-like, dungeon crawler, tactics... not everything hit for everybody but they were truly ambitious and their output was diverse in a way it hasn't been since. Team Andromeda, Climax, let alone all the arcade divisions... it just seems like all the spark left Sega. Even regular collaborators like Treasure... gems like Dynamite Headdy and Guardian Heroes are almost completely unknown nowadays.
Sonic Mania, Shenmue 3, SoR, Wonder Boy and the Panzer Dragoon remakes are all a valiant start in the right direction but it seems like they've passed the point of even obscurity. Everything is small scale and retro not fresh and big and bold. I can't blame anyone born since about the early 90s for having no affinity for Sega.
My big wish is that Saturn emulation is cracked to the point that we can have a Saturn classics package on Switch; if not, polished-up remakes as many of these games are still terrific except for the lack of transparencies. NiGHTS, Guardian Heroes, Shining Force III, Shining the Holy Ark, Shining Wisdom, Daytona, Sega Rally, VF2, Fighters Megamix, Dark Savior, Burning Rangers, the Panzer Dragoon trilogy, Virtua Cop, Radiant Silvergun, Baku Baku, Dragon Force, Virtual On, Sim City, Myst...
