Speaking of classic 90s PC games, I've so far played a few hours of the new Quake: Enhanced that came out a couple of days ago (for Windows, XB1/X/S, PS4/5 and Switch and only $10). I'm very happy that it feels just like playing the original game. The enhancements are only little things like higher resolution support, anti-aliasing, ambient occlusion and a minimal HUD that don't really change how the game looks or plays and can be disabled. It's not like, say, Age of Empires: Definitive Edition, which went too far, IMO, and re-made the game.
It's the original Quake, just brought up to date a little for modern systems. We've had this for years in 3rd-party projects like ZQuake, but it's nice to have something that's official and comes with the levels and soundtrack. It also includes both original expansions and two newer ones. The only thing that seems to be missing is multiplayer support for more than 8 players, though the original QuakeWorld is included (along with Quake for DOS, WinQuake and GLQuake).
Night Dive Studios (probably my favorite remaster studio) seems to have done a great, faithful job and I'm really experiencing nostalgia playing through the first episode. I think that I'll play through the rest and then do all of the expansion campaigns, as well.
