Interesting topic. I've been trying to remember something I felt truly disappointed with, but it's proving difficult. There are some games I know would have disappointed me, but I stayed away from them then as I do now - the Deus Ex sequel springs to mind, as does Blood 2. Then there are those which I disliked or couldn't really get into. Lots of classics on that list (hint: unhalf-craft).
So far, I've been able to come up with:
Temple of Elemental Evil. It did indeed disappoint me. I could barely play it, it was horribly buggy, but worst of all, it was such a fall from grace compared to Arcanum. I had such high hopes for Troika. Oh well.
Mortal Kombat 4. I remember the time I first played it. It was on a PlayStation. I hated it. I hated the PS and I hated the fact I could only play it on a PS. To this very day my eyes inadvertently roll whenever I read something like "gamepads are so much better for fighting games". Sure. If you're into insane button-mashing. If you're the sort who always preferred Street Fighter to MK. I'm tempted to insert a random insult now, but I'll control myself. But it wasn't only the PS. It was the lame 3D (why not just leave it 2D?), the awkward-looking characters, the Street Fighter-ized-ness. I sort of felt betrayed. However, over the years, I've come to love it. Well, OK, like it a lot. To the best of my knowledge, it's the last decent fighting game on the PC. Which makes me even more pissed off at the fact that the rumored high quality re-releases of the first three games is going to be console-only. You go to hell, Midway (or whoever currently owns the rights, since Midway is dead)! You go to hell and you die!
Also, this seems to be as good a place as any to express the desire for MK 1-4 (+Trilogy) to appear on GOG in a nice package. Pretty please?
Starship Titanic. I suppose I was expecting too much. But just to be clear, I don't think it's a bad game.
Sin. See above.
Soldier of Fortune 2. Now this I found almost personally offensive. I spent about twenty minutes with it - and I'd like the last fifteen back, please. It simply shat on all that was good about the original and was unplayable at times because of how bug-ridden it was (my brother finished it, so I got the full report).
Wargods. For the longest time, I thought I'll never see this game. And there was so much to be excited about - did I mention how much I love MK already? So much potential. Well, as you have probably surmised, it was a big disappointment. Curse you, Midway. Again.
<probably more [Midway games :p] to come>
