After playing way too much of this, I’ll provide my take on it. I started out solo and then switched to multi-player PVE, I have no PVP experience.
I don’t mind the harvest/craft/build part of the game. The progression in this regard seems really good. Higher end items can take a lot of material, and this is where a clan can really help. I ended up stopping my solo game because of the cost here. Certainly doable solo if you have the patience, but when you have a few people helping it is a lot faster.
Building can be a bit quirky, and I really wish they gave you the option to pick everything you place back up within a short period of time (10-15 minutes). I find it tricky to place some things correctly, and for many items the only way to try again is to dismantle and build a new one.
Regular PVE combat is okay. I found most of the opponents pretty bland. More damage sponges rather than tactics. Not that there aren’t some tricks, but for the most part it is combo then dodge/block and repeat until dead. Shield opponent gave me the most problems until I found the axe.
Bosses are a real mix. Some of them are really easy, and some can be a bit challenging. It feels like they are meant to be done while leveling up, but I didn’t fight most of them until after I hit 60. This made several of them feel completely underwhelming. Not sure how they fix this. Some can be a lot of fun, our clan had a great time taking down a dragon one evening.
World bosses are a mix. I solo farm several of them now. The easiest takes me between 5 and 10 minutes. If it will take me more than about 15 minutes to kill one, I don’t have the patience. You might be able to solo them all, but there are a couple that would be extremely difficult or take forever (at least for me).
I do think the end game gear progression is broken. All world bosses share the same loot table, so you can get anything by just farming the easier world bosses. The various high end gear pieces are also very similar, so there doesn’t feel like very much end game gear progression.
The world is pretty cool. There are certainly a lot of areas to explore, and I’m constantly finding something I didn’t see before. The ghosts can be interesting and even surprising. @Spect and I were running around one evening and found some ghosts that had a bit of a timing puzzle attached to them. I wasn’t expecting that type of thing in this game.
Loot, aside from the legendary world boss loot, is very boring. Figuring out a puzzle or clearing a camp, only to find 15 stone and 30 plant fibers in a chest is underwhelming. You definitely have to appreciate the journey more than the “reward” here.
With respec potions being pretty cheap, I use two builds, one for fighting and light harvesting and one for dedicated harvesting. An encumbrance/survival build can make harvesting runs way more time efficient. I should have a 100% fighting build, but haven’t had the patience for that.
Certainly happy I bought it and I’ve had a great time with it. I didn’t play Ark, so I don’t know how it compares to that. I think there is a lot of fun to be had. If you don’t like to harvest/craft/build, then I’d highly suggest you join an active clan that can mitigate that need (we are happy to take you on Kono’s server). Solo is certainly viable for almost everything (maybe everything).
