Pick this up this weekend.
It is a lot like Ark, minus the crazy dinosaurs and massive amounts of early deaths. The pace feels slower too with a bit less to do except building stuff early on. Part of the reason I liked Ark, was the dinosaur taming was a major part in conjunction with the base building. Here it feels like mostly base building at the moment. Thralls.. aka slaves, aren't worth trying to get early on as you really don't have the resources to make them do anything you couldn't do yourself really.
On top of that, some resources are retardedly hard to get. Specifically bark as an example. Damn drop rate is as a secondary drop off tree's with the pickaxe only. Even with better pickaxes you only ever get 1 out of a successful attempt. Considering every high end item requires bark as a base component at some point, it's a MASSIVE bottle neck for building shit.
Also, the recipes and crafting timers all seem a bit more worse than Ark. Most things are a 4 to 1 ratio or worse, compared to Ark where most things are a 2 to 1 ratio. Meaning it takes a lot more base resources to make shit. Some of the quantity amounts are just absurd too even for low level crafting items. Then again, the starting areas are relatively peaceful as compared to Ark, so harvesting is sort of "safe" but unlike Ark, you can't tame dinos to make harvesting easier either. To me the game was much easier than Ark or Rust in the beginning. I didn't even die once, nor anyone else. Many things are argo, but many things aren't. You also have good line of sight to everything for the most part so you can easily see things to avoid them. Also almost nothing but crocs chase you into the water so if you are getting chased by anything but a croc you can run into the water and they will break off.
I also am paying for a sever, and the servers out there are flaky as hell because the game code is flaky. The game keeps corrupting DB files which drops the server offline. PITA is what it is right now.
Can definitely tell the game is in a very early state right now. Bug galore, lots of crashes on both the client and the server, balance issues abound, and just really lacking much in the way of content. Also the base map is really small in comparison to Ark as well. The game isn't completely bad, just very rough right now.
