So I take it this is about games we bought and didn't care for afterwards, regretted buying them?
If so, then I guess it might be
Demon Stone for me. I knew it wasn't liked that well, and I read a few lukewarm reviews and watched a gameplay video but I still thought part of the dislike for it was due to it not being a proper D&D CRPG and I hoped it might be a guilty pleasure, maybe even something similar to Enclave. But sadly I couldn't find the gameplay with a magnifying glass. The fixed camera is horrible, the controls are horrible, the railroading is horrible, it doesn't seem to be more than a bland clickfeast that's less fun than even the worst Diablo clone. Besides, it performs quite badly on my low end machine for such an old game, so I can't even enjoy the graphics. :(
Other games I bought and don't care for include Age of Wonders and King's Bounty, but then again, I never expected much of them, with Strategy being one of my least favorite genres. Don't even know why I bought them.
SimonG: Am I the only one who really likes a lot of the games mentioned here?
I don't know about "a lot" but I really liked "GK: Sins of the Fathers", I also enjoyed "VtM: Redemption" more than I thought I would and despite of its flaws, and I think "Stonekeep" is okay, too. "PoP: Sands of Times" seems cool but doesn't perform too well on my machine, I hope to play it with a better graphic card one day. "Septerra Core" was fun for a while back in the days but I agree that the combat got too repetitive in the end.
