Hi AtariAge, I just was recently introduced to Atari 2600 development and wanted to share a few things I came up with...
An adventure-type game with a fairly large over-world along with some randomly placed dungeons to explore.
A simple two-player competition to collect points and power-ups
A random "don't crash into things" space type game.
Basically, driving in New England.
In any case, the games are attached and ready to go, along with some "labels" I made up. I'd also be happy to share any source code with anyone who's interested!
Have fun and let me know what you think. Thanks for letting me join in the fun on AtariAge.
