I bought Subnautica and PLAYERUNKNOWNS BATTLEGROUNDS, two very different games but both worth the money, particularly seeing as I bought them both from the Indian steam store!!
word of warning, early access games sometimes dont get finished, I invested in two, one is as good as dead, and the other 4 years later and still waiting.
I think this has a release date for February on all platforms.
Know what you mean though. It's a [censored] laggy mess at the minute. Even GTX1080 owners struggling to stay above 30fps. It's terribly unoptimised right now, but I can see the promise in it.
I got Wreckfest early access too (Next Car Game), and that's awesome. It wouldn't bother me if they didn't finish the whole "career mode" side of things. I just like the UK Bangerz mod.
