Clandestiny, because of the recycled puzzles from 7th Guest, 11th Hour, and other puzzle games at the time. And, it wasn't a good game.
Knight's Chase (don't remember the subtitle) One of the worst reviews in PC Gamer at the time, it was a bit of a mess. Was not good and I never finished it.
Xtreme Paintbrawl 1, Xtreme Water Sports, just most of the products with Xtreme in the title that were made by Headgames and they were bad to the bone. We're talking about a batch of games that were stupid or unplayable. Look them up if you don't believe me.
Overblood, I've some playthroughs on Youtube. Just no way on earth, I'd rather sit through a math class, and I graduated years ago.
Peril Island, bad shooter from the time Doom was the best game to copy.
The Lawnmower Man game, the CD version, it looked like a hot mess from the review I saw on Youtube.
Suspended by Infocom, I never was able to finish this text adventure. It may be the only game I really hate besides....
Clock Tower: The Struggle Within. I liked it at first when I played back years ago, but it was so boring. It was the first game in the series I had played, so I didn't know how to hide or defend myself in the game. Just bad, worst in the series of Clock Tower games.
I could name more by going through my stack of PC Gamer magazines from the 90's.
