The Sega Dreamcast was a system that had some really cool and innovative games. However, the console never had as much widespread appeal as the PS2 or Xbox.
Dreamcast was like an arcade console in the home. As Sega produced many games and brought them over. Third parties released their arcade fighters on the console and they were arcade perfect or better like Soul Calibur. Back when games were about instant fun because they had to be to draw you in.
Every console we play today is more about length of a game and added side missions or fluff to lengthen the game than arcade as many of the games aren't arcade like. There are arcade like games there. Especially fighters. But these consoles don't have the same feel as an arcade company that made an arcade like machine. Dreamcast was the end of an era as most gamers play at home, most console games don't release in the arcade and multiplayer is through an online connection that kills that in person social gathering.
Gamers like myself that grew up on arcades, can tell the difference from popping tokens and nickels and quarters at arcades and just pressing start with a controller. Dreamcast had that feeling. It had a short life but it sure left an impression. Which is why I have two units to make sure. Because it's soul never dies(Soul Calibur)
I'm not sure if my explanation below fits why you like Dreamcast. But that's how I felt about it. Even today, there are no light gun games anymore. And today's TVs don't even support them. I have to keep a CRT TV just to keep light gun gaming alive.
And online is okay. But it's like playing poker in person compared to over the internet with a no name and no face opponent. The game is the same but you don't get the poker face looks, the body movement, the physical cards or chips. Dreamcast had that arcade feel and local, multiplayer fun.
If you like survival horror, i highly recommend D2. It’s really cool. Reminiscent of deadly premonition. Great atmosphere and music. Super campy and cheesy but unique. Just emulate it.
I would play a seaman remake today. No doubt.
I think outtrigger is really underrated as a game for the dreamcast. It was quite good for the time.
If I could take two consoles with me into the after life it would be the Snes and dreamcast.
