Morrowind and Deus Ex are two recent ones for me. I disliked both these games on sight. I only picked them up as part of a Steam sale and regretted both purchases.
Morrowind had potential but the combat was so god-awful I did not want to play it anymore. I understand there are mods that fix the combat, but I do not want to hear about them. The day I fiddle with game mods is the day I get myself a sex change. Not that I want to be a woman, mind. I would just have one because I can. Besides, I suspect that even the best mods make the combat tolerable, not good. So, fuck it.
Deus Ex struck me as a game trying too hard and failing. Maybe it's just me, though. Maybe I'm the kind of brainless git who not only needs but actually enjoys being led around by the nose. In either case, on the very first mission I was told to invade some enemy position and was given the impression that I could choose my own way in. Fair enough, but once I finally got to go do it, I had no idea where to go or how to get there. So I wound up wandering around until I found myself in an area where people were shooting at me and I shot back until I died. Fuck this nonsense, I thought. It may be the greatest game ever once you learn how to do it, but I'll never know because i found playing it so unrewarding that I don't want to learn how to do it. Let me clarify that. You could offer me a million dollars and a blowjob to learn how to play Deus Ex to the point where I'll find it enjoyable and I will refuse. I don't want to. Not now. Not ever. That's how pissed the game has made me. All for three buck.
