Okay so I played it for a while and I have to say I did have a lot of fun. Yes it's Early Access, it has some glitches/bugs as to be expected, the performance is pretty bad but as they said they haven't worked much on optimization but it is now their number 1 priority. The UI is a bit ugly but it's obviously not a major issue and I am sure it'll be altered.
Well, gameplay wise, it is good fun, people can say it's DayZ, Rust, Stomping Lands copy etc etc but it does feel very unique. The combat isn't amazing or complicated by any means but it was pretty responsive compared to many other of these Survival MMORPGs I have played, that being said it's a lot of fun. I found a couple of guys, one was Russian and one German, we made a tribe and a small base of operations and we just hunted a whole lot of shit and gathered resources. We went into the sea and managed to kill two giant sharks by luring them to the shore, stabbing them with our Spears and shooting them with Slingshots which was pretty funny, the Russian guy got eaten in the process.
Killing the Dinosaurs was fun, I threw some spears into a Stegasaurus's butt and we also hunted some players. We found one guy by the beach and the Russian guy shot him in the face with the OP Slingshot, it knocked him out instantly and we dragged him back up the beach to our house. We took him inside, layed him on the bed and shitted on him ( literally, your character automatically shits every now and then but you can also trigger it at certain times with the Z key ). Hee woke up after a while of us pissing about with him, we punched him out again and then dragged him outside where we used him as target practice for Spear throwing, he died pretty quick.
Certain creatures/dinosaurs will also fight eachother as well, but the real lure for me is the fact you can tame a whole bunch of them. It's a slow process and it's going to be difficult to tame the bigger and more dangerous Dinosaurs but it will be awesome once you obtain one. They level up just like you and of course as shown in the trailer can be ridden if you have a saddle for them. The saddles require higher levels to craft though so I imagine the real mounts of the game will be more of a high level/end game thing. Some Dinosaurs/Creatures have their own abilities, like the Dilophosaurus, that little one from Jurassic Park that spits shit in your eyes, I also saw a giant scorpion thing that has a sting that can paralyze, which could actually be very useful for helping to knock out and tame a Carnivore.
I only managed to tame a low level Parasaurolophus ( being low level myself and the fact it's a pretty whimpy Herbivore ) but it was fun getting it to follow me around, carry my shit and help me kill things.
My verdict is, it's a fairly decent game but don't buy it yet if you want good performance, even a lot of monster rigs aren't running this game smoothly on highest settings and cheaper systems struggle to run it smoothly even on lower settings, that being said they've promised their first and foremost priority at the moment is optimization so we should be seeing performance boosts soon. The game already feels unique and it certainly has a lot of potential, it's definitely one to watch in this Genre IMO.
