I was going to type up some long response, but honestly I don't think that's needed here because it's exactly what most reviews have said.
Here's the breakdown based on my first 4 hours:
- It's almost exactly what I thought it would be. I have no idea what people were expecting, but I don't blame the developer for some of the disappointment as I'm getting almost everything I thought I would based on all the videos I saw.
- Visuals are a let-down (on the ps4 at least). Texture pop-in is quite distracting when flying, and animations aren't great. I hope the draw distance is better on the PC.
- The FPS mechanics are clunky, but that might just be me not playing many FPS on the PS4. Again, probably better on PC and there's not much in the way of shooting (yet)
- The first few hours are basically a loose tutorial that introduces you to the game mechanics without actually feeling like a tutorial. It was really well done and something that fits really well with this type of game.
- I can see that after getting through the mechanics, and playing for a while, that things may get repetitive... so many out there are going to be bored after a few ours, but some of us will still get a lot of gameplay out of it.
So I know it's going to sound crazy, but for me the game it reminds me most of right now is Just Cause 2. Is it the same genre? Nope. Does it have cool explosions? Not really. So what in the hell do I mean by that?
Pretty much every single bad thing you can say about NMS was also true about JC2. JC2 had next to no campaign, it was incredibly shallow. You visited copy/pasted bases that were pretty easily dealt with. There were bases you could destroy everything in, which could be fun but also was very repetitive. Despite all of this "shallowness" I dumped more hours in JC2 just messing around than any other game during the 360 generation. The map was huge, and even though everything I did was very repetitive I was never really bored. I get the same sense out of NMS, if to a lesser degree. I can understand people finding it boring, and I myself will get bored of it some day, but right now I think most people that don't like just don't like a game that throws a handful of mechanics at you and gives you the freedom to do what you want.
The ONLY thing that's really holding me back from recommending it fully is not having a f'ing map. It's so easy to get lost in caves and there's no good way to find your way out. A diablo style mini-map that fills in as you visit things (you know, like an actual explorer would do) would have been perfect. I'm so mad that such a simple omission might potentially ruin the experience for a lot of people, but it really needs to be highlighted. You WILL be pissed off that there's no map, and it's a damn shame.
Anyway, wait till it's cheaper but I wouldn't discount it completely.
