My list:
Diakatana (PC)- Didn't even work on my (at the time) high end system
Trickstyle (DC)- it was just shite
Virtua Striker 2.000 (DC)- The game did no justice for the sport, nor did it have the nice feel of its arcade bretheren
Battle Arena Toshinden III (PSX)- Really, did they even try for this one
NHL Open Ice 2 on 2 (PSX)- Another arcade port that lost something in the home translation. After the excellent ports of Hang Time and Jam TE, I thought this one would be good.
Corvette (PS2)- I was expecting way too much from a value priced title
TNN Hardcore Heat (DC) [Actually Buggy Heat]- It seemed like a good idea, an off road racer, and I enjoyed TNN Hardcore 4x4, but it didn't play up to my expectations.
