But there was a time I played a lot and if you get nostalgia you can turn back time with :
A Commodore Emulator : Vice is a good choice if you want to play your old school games like Sid Meyer's Pirates I have even bought a joystick to get this C64 feeling back
A Dos Emulator : Dosbox works fine for me when I want to play "Civilization I", "Sim City 2000" or "Railroad Tycoon I" again. The sequels are most of the time too complex for me (or should I name it overloaded?)
ScummVm: ScummVM allows you to run certain classic graphical point-and-click adventure games like "Monkey Island"
(C64 Pirates, released 1987 (screenshot from mobygames.com))
