... give some proper Bubble Bubble ...
my shitty pirated floppy disk was full of viruses back in the day.
Also, if it hasn't been said yet:
Elite (so we now have PCs like 18000 times as strong as back then, but, apparently, transitionless space-to-surface flight takes too much cpu power nowadays)
Battlezone (as we discussed in IRC lately. one of the best games ever [the new old one, not the old old one]. it's fast, it has a cool story, it's tactical, its hard. awesome

also, if anyone knows other gems like battlezone (first person action combined with real RTS decisions), point me in the right direction, those games are so damn rare.
