I remember that Shuttle game, after you launch you had to open the Bay doors to cool it down, it had like 5 million buttons and I always managed to burn up coming home from what I remember, but still crazy sim for back them, it was pretty cool just pressing buttons and having no idea what they do.
Also another amazing game years ago was called Carrier Command, Amiga and PC, I don't think many people will know about this game, but there was 2 futuristic Aircraft carriers and a massive map 100 Island, the idea was to track down the enemy Carrier while setting up a supply infrastructure, it was really amazing...far to complex to explain...
