A promise unforfilled is not a lie.
And they can still make good, except to you who accused them of lying.
Im pretty sure when they tell us "we only cut some levels", and it turns out to be the whole dungeon, we can call it a lie.
Im not mad about unfulfilled promises, the game is amazing anyway. But I dont like when someone lie to me. Im ok with "sorry, we didn't have time to finish, we'll add it later". Shit happens, i can wait, no problem. But when I expect dungeon being in game, just a little shorter, and I'm all excited to explore it, and then suddenly realize that there is no dungeon at all, it is kinda annyoing. I could even become angry at Larian, if the rest of the game wouldn't be so damn amazing.
