This is going to be a hot take
but IMO the Dreamcast is one of the most overrated consoles ever but it was overlooked and underrated by many in its prime.
I still own a Dreamcast and I've played the hell out of some shmups and such over the years on it, but generally nowadays I only take it out when my friend comes over so he can play that dumb Jojo game of his....he even made a topic about it here :) real talk tho visually that game looks stunning, I just suck at FGs.
Here's the thing, ok don't get me wrong, I love the Dreamcast.
I single handedly promoted the Dreamcast in Macedonia in a magazine I worked for
I was THE only person in my entire country to REVIEW games for the Dreamcast back then.
But after Dreamcast lost most of its exclusives to multi platform releases it just kinda became obsolete. For example if I want to play Batsugun on CRT or Battle Garegaa on CRT my only choice outside of emulation is my SEGA Saturn.
If I want to play Psyvariar 2 on the other hand, I can either do it on DC or PS2...and the PS2 version has superior gameplay mechanics with the auto roll.
Many tho not all shmups moved to PS2, the system was too focused on one on one fighting games and while there are still exclusives that remain on the DC I feel it's not that relevant for me to always have a Dreamcast out anymore.
Canon Spike? Sure, it's a lovely game but ultimately kinda visually bland and not very exciting for me personally. It's not a game I absolutely must keep coming back to.
Bangai-O is phenomenal, but I'd rather play it on emulators with a dual analog controller.
The Sonic Adventures are jank, we're not even looking at those....and I gave SA2 10/10 back in the day at that magazine, jesus....
The system has far too many arena fighters, Spawn, Heavy Metal or whatever it was called, Outtrigger...
It's just a different era of arcade games
no 2d beat em ups, honestly Dynamite Cop 2/Dynamite Deka and Zombie Revenge are ok but they're not as punchy or refined as my favorite 2d beat em ups for me to keep coming back to.
I dunno I'd rather go back to the Saturn, Mega Drive I play a ton than the Dreamcast.
That's not to say I don't play it if I have multiplatform games I own on that but not other systems and want to experience them on CRT like Trizeal, Under Defeat, Zero Gunner 2 and Triggerheart Exelica (tho i own these on Switch but it's emulation). So I STILL play it, I just don't feel it's that important as a console anymore.
I love many games on the DC, but they're not the type I'd replay all the time.
On the other hand those that I would, its arcade roster is either also on PS2 or Xbox and GameCube, that or it's all fighting games and arenas and I don't care about fighting games and arenas.
Cosmic Smash is still a great exclusive but how often do I feel like playing a game like that, tho it's a ton of fun when i'm in the mood for it.
