Below are a couple of games that I am aware of, and own, for PC. These are great for your Peanuts collection and anyone can play them. Great graphics, and simple to learn. I've placed a link under each to Amazon.com, where they may be purchased.
I found this game at Goodwill. Didn't even know it existed. I picked it up for a collector's item. It works on Windows Vista & Windows 7 if you know how to get it working. I don't have any in-game photos at the moment, I'll try to find some later on.
I know this isn't on PC, but I got a scan of the Snoopy and the Red Baron game for Atari 2600 and I thought I'd share it here. Both front and back are viewable.
