Lmao, Codexian pissing contest of posting THE EARLIEST EARLY 3D GAMEZ!" Having said that, including KotOR in the OP was pretty silly.
I think when most people mention "early 3D" they mean something around 1995 - 1999. Jedi Knight, Die by the Sword, Trespasser, TombRaider 1-3 and the Lara Corft wannabes.
Objectively, this is horrible.
But it undeniably has an unique atmosphere to it. Low resolution 3d really forces your imagination to fill the gaps and humanoid forms always look disturbing. Spooky.
Made non-horror games of that time much scarier than intended. No wonder there's a fair number of indie early-3d horror games.
