RTS. Used to be a very competitor genre. C&C, AoE, WC… every studio had an RTS or one in the works. Now there is only SCII left. I remember playing games of Red Alert and Total Annihilation they would last all day. Fuck, somone port Red Alert to the Switch pls.
MMORPGs. They get developed now, I guess, but it’s all pay to win garbage. It’s not even the same genre IMO.
Space/tech simulators. We used to have X-Wing, Descent, Freespace, Mechwarrior, Fighter Ace, etc. There used to be an entire SECTION in stores that contained joysticks of all different kinds. Now we just have train simulator with garbage DLC skins.
Realistic, tactical, team-based FPS games. Rainbow Six, America’s Army, etc. The “one shot” kind of FPS where you didn’t just jump around like a bullet sponge.
Steam has been GREAT for small indie games, platformers, and new concepts like KSP. But we’ve also lost a lot as the major studios have all converged towards mass market games.
