My dad had a 32k CoCo. The games were pretty bad for it, with the best being mega-bug, or something like that.
The C64 had a ton of great arcade ports, that were often better than those on the Colecovision. It also had all of the TSR RPGs, along with the likes of The Bard’s Tale and Phantasie. There was also a really cool space ship captain game callled PSI 5 Trading company. You hired your crew and had to manage them as you took flight across the Galaxy, evading pirates and keeping your cargo intact.
