I knew you didn't mean Rocket-Propelled Grenades, but that is what I immediately thought of.

You could always play the classic text adventures, using DOSbox. I played them on my Amiga. Best ones I played were the ones from Magnetic Scrolls (The Pawn, Guild of Thieves, etc) and Infocom, like The Lurking Horror, and many others, including the Zork series (which I did not enjoy so much). There was also The Hitchhiker's Guide to the Galaxy, which you surely would like, Slartibart.
