We got the C64 Light Fantastic set, with the game gun and a compilation tape of shoot-em-up levels from various Ocean games, including Robocop,Platoon and Rambo III.
The main games I enjoyed playing on it were Ghosts and Goblins, Slap N Tickle (which also came with the set, and was part of their Shoot Em Up Construction Kit tape), Back to the Future II, Gremlins 2, Batman the Movie, Globetrotter (wish I could find a playthrough of it somewhere on youtube) and of course Dalek Attack (the last game I got for it before my family decided we had to chuck it out for a more advanced model).
Sometimes I'm tempted to get that new mini C64 set, though it doesn't have any of the familiar titles I remember. If it even had Ghosts and Goblins on it, I'd probably snatch it up today.
