So far, early favorites from suggestions include Park Patrol, Toy Bizzare and Space Taxi. And boy, does Toy bizzare in a quick 4 second intro melody show why the SID is so loved. The level-start melody is damn near epic.

I'll tuck in on some of the RPG suggestions but since they take longer to evaluate... etc... however I can see why folks like it. If I can find a cheap c128 brick I may have to dig it out and set it up. It's missing a key, but it's an inconsequential key and the parts underneath still work anyway.
