I liked Baldur's Gate, loved Mass Effect and KOTOR, but Dragon Age just bores me. I think it's because of the overly long combat sequences, as the combat is just dull. I could forgive that similar dull combat in KOTOR because even if it is mechanically poor, it just feels awesome to force choke people and kill entire fields of enemies instantly with force-powered lightning storms. In Baldur's gate it's poor mechanically, uninspired visually, and completely unexciting to boot.
Since someone's already said that though, I'll also say Fate/stay night, which I actually have open in another window right now. I've been playing and enjoying a lot of visual novels since I got into them recently, and this game is often touted as the best (or at least one of the best). I even liked the predecessor, but something about this one just puts me off. I'm going to finish it, I've put too much time and effort into it to not do so, but god-damn it almost feels like work at this point.
I think the problem might be the main character, since he's both an asshole and an idiot, and I just don't care about what happens to him at all. What's worse is, all of the characters (and even the game itself) seem to think he's awesome, and that we should all aspire to be like him. Something about that pisses me off, and it's compounded by the fact that the game is so long (and he's in practically every scene, being the main character and all).
Ugh... Now that I've finished typing that up I have to actually continue playing it, I guess. I'm on to the 3rd and final route, so I can't be too far from the end at least.
