It's the most confusing part about it all IMO. I never thought it would be the source of so many weird debates and arguments, but here we are. I'm still not sure WHY it's such a target, it's really bizarre to me. I guess it's just a little bit of everything that people have mentioned above? I really don't know.
It's awesome seeing folks talk about a game having SO much to do in it, I mean, god forbid a AAA priced game has a ton of content. It SHOULD be that way, and a lot more common.
It's also awesome seeing a game be praised more by its community and fans, as opposed to review/game outlets. It happened with Alien Isolation and many others, and it's always wonderful to see. Just another reminder that your own opinion should be more important than anyone else's, don't miss out on things that you could potentially enjoy just because of someone else's opinion/review. If you're interested in it, check it out and see for yourself. If you're worried about getting something and it "being a waste of money" get it on Steam, you can refund it if it's genuinely not for you, but at least you gave it shot!
I look forward to picking this up in due time, which works perfectly as I can't be too irresponsible at the moment, lol.
