Even though I stand by that Tempest 2000 is the best game of 1994 and that Doom 2 and Sonic 3 and Knockles are up there, I totally forgot some of the runners up:
Virtua Fighter 2 is a top 3 3D fighting game imo. Daytona USA is a phenomenal arcade racer, with one of my favorite video game soundtracks of all time. Ditto Sega Rally Championships, which is actually my favorite racing game of all time. Castlevania Bloodlines and Contra Hard Corps are great additions to two of my favorite franchises. And then I cannot fathom nobody talks about Donkey Kong for the Gameboy. That is one of the greatest puzzle platformers of all time, and the greatest Gameboy game to star the plumber. Also the best game of the 90s to feature Donkey Kong.
