I think that was Advanced Dungeons and Dragons. There was also a maze like game called Night Stalker where robots would come after you trying to kill you. Baseball was a lot of fun, I used to play that with my bro a lot. Ever play Buzz Bombers, Bump & Jump, Lock & Chase, Carnival, or Mouse Trap? One day a new game magically appeared, it was called Kool Aid. My parents had sent away for it with the UPCs of the Kool Aid packets. The KoolAid game was really hard.
Was this it?

A couple seconds in it warps to the maze.
I created an Intellivision thread back in the day, back when I was Nachtjager.
Please feel free to revive it. I can talk Intellivision all day:
