Game is great so far, v funny, good writing and atmosphere. From first minutes in character generator you got this feeling playing successor to fallout 1 and 2 in spirit, I love it.
HDR is in the ini files settings but not officially in the options yet, my guess its coming.
As for buying - I'm really perplexed that its not been talked about here more. Get it on xbox beta app in windows 10 store.
Its fucking awesome 1 buck for first month, then 5 for next ones- that includes shitton of big quality AAA games for you to locally download, install and play, plus as many high quality indie. I have been pretty much exclusively playing games there for last four months and fired up steam maybe few times to check deals etc. The amount of games on xbox beta at the moment is massive. With new titles being added weekly and only one or two (usually ones no one care anyway) disappearing. This service is great for trying new games I would never consider as well. I even bought few on steam after trying to get all dlcs etc. Just check the games lineup here
