Hi!
Interesting question and interesting list
I think that you could add:
- Bubble Bobble
- Gobliiins
- Hot Rod
- Indy Heat
- Lure of the Temptress
- Marble Madness
- Rainbow Island
- Rod Land
- Simon the Sorcerer
- The Great Giana Sisters
- The Lost Prince
Tower of Babel features a Zapper that can "zap" objects, would that qualify as a "gun"? If not, add it to the list! What about Loom, there are some "fights" with some spells IIRC. What about Pang, in which player fire a kind of harpoon?
Cheers!
