Ages ago (way back in 1990-91, I think) one of my flatmates had the game OIDS on his computer. It ran just fine on a Mac Plus and on the new Mac LC’s that had just come out. Good memories of the flat all taking turns to see who could get the highest score.
Any now I find that there’s a version for Mac OS X available from Xavagus Prime Software. I downloaded it and all the game playing memories came back. Unfortunately, the old game playing reflexes haven’t come back with the memories – can’t seem to fly anywhere near as well as I once did.
