I've never played any of these survival games - is there a consensus on the best one out there currently? I've got a couple of friends who play Don't Starve, Rust, and ARK, but I haven't been able to get a good feel on what the conventional wisdom is.
Personally I felt like Ark was the one that was best implemented, most robust, and is also being frequently updated and improved every month. It seemed like even several months and a few large patches ago there was a very long grind of content if you were interested in putting in the time. Iit was also probably the most interesting for a single player out of those I've played, but I think it would also be much better if you had a group of people to play with since there are clan fort mechanics.
I haven't played them all, but I've put time into DayZ (was very broken, but interesting in concept), Infestation (was better than expected by the time I played it, it was a massive disaster when originally released as WarZ), Don't Starve (didn't hold my interest much at all when I played), H1Z1 (not nearly as polished as I would have expected from Sony, and lost interest after ~15 hours), , Asteroids: Outpost (very unfinished), Minecraft (amazing), and maybe some others.
I'm interested in trying out Subnatica, since it's very different from the others with it's lush underwater environment and has had a good reception even in Early Access.
