Feel like Stunts is such a sleeper retro game so many played and nobody ever talks about. Incredible fully customizable levels with massive obstacles rendered in 3D. In 1990, 3 years before doom.
I sometimes have to consciously remind myself that I haven't played chrono trigger until 2005, or that I clocked some unreasonable amount of hours playing rise of the triad, Star Wars dark forces and Ultima underworld, rather than the whatever's on the list of top 90s video games.
