I've been watching you/Kalrakh for a while, and I do think the game definitely deserves GOTY, but the game definitely also has a lot of flaws. I've come to realize the key difference between you and I (As well as I presume Kalrakh, Bowie, etc) when it comes to this game is an integral difference in how we play/perceive the game..
You play the game for the story, whilst I play for the tactical combat. I did enjoy the story but it's not why I'm here. Correct me if I am wrong in my assertion.
I loved DOS1 to death (Having beat it ~5 times) not for it's story, but for it's highly tactical combat and wonderful progression system (4 of those playthroughs were modded however).
I loathe playing DOS2 as the reason I play it is for the tactical combat and progression, but both of those areas the game.. Really rather sucks pretty bad. If you don't think so then I'd just like to point you to the various in depth articles on the subject posted close after the game's release. If I played the game only for the story then I'd probably just lower the difficulty. But that's not why I'm here and that's where the game has failed spectacularly in my eyes.
Don't get me wrong, I do agree that the story is a major part of the game, but I'd just like to reiterate that it's not why I'm here to play the game.
You might make the argument that this means the game isn't the one for me, but it along with it's predecessor are among the very, very few games that occupy this space.
Instead of asking for the devs to fix it all I'm actively working on a mod to fix all of the issues I have with the game.
