Hmm... Lotta things listed here that I have to agree with as really bad. (Except for Face Off hockey - I had the C64 version, and liked it well enough, but never got a copy of the Amiga one that worked!)
Days of Thunder- At least this game gave me and my friends a hearty laugh as the gauges just randomly bounced around and the engine sample looped with a pop every half second, or so. That, and we'd sneak up behind each other and scream "Cole, ya look like $hit out there!" Still one of the worst racing games I've ever seen, though.
Some NOT mentioned:
Dangerous Streets - What kind of crackhead would package this game in a gamer kit??? It was about the worst street fighter clone I've ever had the misfortune of seeing. Even the Amiga version of Mortal Kombat (back-back-forward-diagonal/down-forward-back-button to duplicate a simple 1 button move in the arcade) was better than this!!
Bill & Ted's Excellent Adventure - Another trainwreck of licensing... It was bad enough it was actually pretty funny, though.
The Amiga version of Scooby Doo left a lot to be desired, as well. In fact, most licensed games had a high potential to suck. Looking through my disk catalog in the section titled "Why the hell do I still have this?" more than half appear to be licensed titles.
Other noteworthy titles include what I think was supposed to be a platformer called "Fire and Brimstone" and, of course, the summer games knockoffs, like "Summer Olympiad".
