...but no gamebreaking bugs.
I thoroughly enjoyed it too, but only after I'd edited the executable with a hex editor to change one 'word'. Without that edit the game crashed upon trying to leave the bar for the first time. Every time! I'd call that pretty game breaking.
There were numerous other little niggles, a couple of quests that were impossible to complete (some because it was possible to perform some of the quest advancement triggers before reaching that stage of the questline, meaning that if [and based on their positioning, more likely when] you did them was no longer possible to trigger the advance, some simply because you happened to take the 'wrong' route to get to the quest location, and some ... god knows why), and the 'linear' nature of the game meant that no matter how quickly you completed the game, how few steps you took to get there, the character was always at the same stage of 'psychosis' by the end. That broke 'immersion' in a big way, for me.
That said, some of the quest lines were great (e.g. the 'crucifixion'), and overall I was pretty impressed. I certainly got my money's worth out of the game, and, once I'd tracked down how to fix the initial bug, was not at all unhappy I bought it at launch.
I guess, with these new patches and content updates, it might be worth taking another look at it, see if the couple of things I never completed are now properly fixed.
