I'm a fan of the homebrew game Four-Play, and I recently tried the homebrew of Yahtzee, and this got me thinking about what other games would translate well to the Atari. One game that came to mind was Operation. If I remember right there is an Operation-esque level in M.A.S.H. Here are some other ideas:
Risk: Would Risk be possible on the 2600? I think I remember a version of Risk for the C64, but I can't remember if it was good.
Hex: This looks like it could be a fun game, and perhaps doable on the 2600: https://en.wikipedia...ex_(board_game)
Tri-ominos: I have find memories of this as a kid. Have there been any domino games for the 2600?
Go: I picked this up from some Chinese friends. It looks like Othello, but it's different!
Stay Alive: Honestly, not sure how this would work, but I did love it when I was a kid, and i think the concept could make a decent game:
Trouble: The pop-o-matic made this cool, but I'd play a video game of this
Any other ideas?
