Rotor from Arcana first came out in 1989. You must pilot a Roto-raider craft behind enemy lines. To get you ready for battle, you can try out the six simulator tests. Then when you've earned sufficient "prestige units" you can go head-to-head with the enemy. The game itself is very much like Thrust - you're battling as much with gravity as with the alien emplacements.
It's not just the poor scrolling (which sometimes disorientates you) or the sparse effects which make the ST version less worthy, it's also the fact that Rotor has OIDS as a direct competitor. OIDS is a far superior game, but anyone with a liking for Gravitar-influenced action should check it out anyway.
