It's early access, got that?
This game is prettier than the others, more detailed and has a lot of potential but of course it is still in early access, so don't expect the finished, polished article just yet. There are a lot of aspects that are identical to the original games, you'll either like that or dislike that, me? I'm an obsessive with hundreds of hours playing these games, I think when this is finished it will be the best of the series by quite a margin so let's not be too negative this early. The game crashes occasionally but fixes have been coming thick and fast and all seem to be on the right track.
If you liked the others you'll like this and the longer the early access goes on the more you'll like it.
