I would suggest Dune 2, which is an awesome strategy game. Games like Worms, Monkey Island, Monkey Island 2 and Formula One Grand Prix are cool games as well.
If you have Mortal Kombat 1 and 2, Desert Strike, Sensible World Of Soccer, Soccer Kid, Superfrog, Cannon Fodder and Super Hagn-On on original disks you can find installers for them (and lots of others as well) at
