Oh, wow! I dunno why, but after all our research, it's cool to realise there's a space trading game I've never heard of at all.
That said, Atari ST was a platform I never had, so it shouldn't surprise me TOO much.
Actually, the engineering repair systems for OiS were inspired by the old Microprose game "Lightspeed" (or its re-release, "Hyperspeed")
But given their age, it seems quite possible they took inspiration from Sundog.
Oh, niiice! Thanks! I love Scott's stuff. That'll go on my to-watch list.
