Well given the amount of time this game has been out (its now been in Alpha for over 3 years!), the fact they are still working on texture, sounds and lighting enhancement is frankly amazing.
This is basic engine stuff that should have been addressed well before adding in new loot items and the like, also the sheer amount of bugs that still exist is also mind blowing again given that it was released in Dec 2013.
The game has so much promise, but its been totally ruined by lacklustre development, awful support, mediocre choices and no end date for the process.
