Below the Root. My neighbor had this on Commodore 64/128 (can't recall which one). Took forever to boot up but what did we know in 1988? http://www.youtube.com/watch?v=uLsJBmk_TMY There was also a text game called Road Wars or something similar; you had to build up your fleet of vehicles, steal gas, etc. Very cool but I can't find any links.
Abuse,Halloween Harry,Sango Fighter,BioForge,Bio Menace !!!,and a certain shmup which i can't seem to remember the name of...it was a horizontal shmup..the menu screen was in a semy 3d font, the mouse pointer was a gold arrow slightly tilted to the left and i also remember that there was a short cutscene after you selected your ship in which it flies through a tunnel and into space.I think it supported mouse only control.
