Procedural generation is a huge selling point with me because once you know a map and know where "the" best place to build a base is, there isn't much point in replaying it. The mobs are reasonably balanced so that they give a challenge, but as long as you're not skipping biomes, they're not ridiculously unfair. Also there aren't any uber pets that make foraging and inventory mechanics obsolete as soon as you get them. (These were reasons why I stopped playing Ark.)

It isn't a particularly flashy game but it does its job well. It has very few bugs and a clear progression. It's also very pretty despite the pixelized graphics because the lighting effects work well.
