The game is hard. Especially early. Especially if youre trying to be ranged (like i was). But this game is nothing like dark souls, and I dont understand the comparison bc combat is NOT the focus. Its a survival game for the first 10-15 levels or so (and that can be 15-20 hours into a game, if not more), and combat isn't even where you're going to get much xp - later on it becomes a way of getting items for crafting, etc but at the outset just try and live in the world, meet the characters, factions etc. I love the atmosphere this creates, trying to avoid entanglements, or sneaking around enemy groups to get to objectives, calculating how much a fight would be worth, and the like. The open world is extremely well done, it is varied (unlike fallout), and exploring feels fun, somehow, not a chore - it all somehow makes it feel worthwhile.
Combat can be a little glitchy, and I have had the game crash on me exactly once. Otherwise its run smooth. The graphics/art aren't mind blowing, but are actually pretty nice. The quests are really solid, but the menu system itself can be a little annoying - for instance, on a side quest for Eva, once you finish the primary mission, you have to remember what she told you if you want the achievement attached to it bc the quest actually appears to continue even though it is no longer in your questlog (this may be an easter egg thing, i'm not sure).
Personally, I have really enjoyed this game. It takes awhile to bloom though, maybe 5+ hours before I was really sucked in and then woah. It does remind me alot of the Gothic series, as well as the Bethesda games.
As someone else pointed out, your actions matter, they can impact the game, and it can take a very long time before you realize what you did. It forces you to live with the decisions youve made, which personally I usually don't do. This makes it infinitely more replayable in my opinion. More to the point, the game makes it fun to figure out how it works and what works best and is fairly forgivable otherwise (like you can't build a bad character, even if you switch from melee to flamethrower, min-maxing doesnt seem hugely important).
Its a rough diamond. I'd highly recommend to people who enjoy open world games. A score of four doesn't really compute for me.
