@ChrisPirillo It's beyond a miracle that not only did #Doom push the technology further in a huge way, but the fact that it pretty much popularized the modding scene with its .WADs and it's still both played and supported even to this day which is a testament to great game development if you ask me.
There are plenty of oldschool 90's shooters but I'd say none of them revolutionized #FPSGames the way #DoomGame did.
Some would argue #Quake did a similar thing but I'd say "Doom did it better"
