I really do like Superfrog, its a good platform game, the kids love the colours and the themes. Shadow of the beast series were ok, too hard and gameplay would make a saint curse.
Spent many an hour playing Stunt car racer with my neighbour on a 60 foot serial cable. There were actually very few games that i actually finished due to boredom creeping in. I liked Ports of Call, i had to disable the manual docking/undocking tugs and all the other annoyances that popped up as they were just too annoying.
Millennium 2.2 was good, finished that one but no good for a repeat as it was too linear. Mike the magic Dragon was a fun game also that i used to spend a few hours on when it first came out
