I've heard lots of stories about the devs and the game itself before buying this, as many comments said this game is a catastrophe to many indie groups who tried the way of crowdfunding. Despite many negative news, i thought "Hey, these days players are surely too strict for the indie groups, why not give it a try, maybe it is fun or what..." Well, after playing the original version and the recent updates, i decided to write sth to those players who are attracted by its infamy. This is my 1st english comment so you may find some mistakes in vocabularies.

The major issue of the game is mechanism, it is very quite repetitive, even the developers added more features like building/new clans/transporting vehicles etc, the game is not interesting to play at all. The major goal of the game is to reach the core of universe, to achieve this goal you need collect the resources, upgrade ship gears, doing some business with other races, sound's fun? Unfortunately the gameplay is slowing, you just walk around to collect resources in one randomly generated planet then go to another, there are some buildings with their own uses in each planet but you just felt like the planing of these buildings are all the same after exploring 2 or 3 galaxies. You can meet this problem in every corner of this game, no matter what world it generated, the tasks are probably all the same: 1, Find a planet, collect some resources and items. 2, Name the new creatures/planet/places you found in this planet to gain cash. 3, Find trading post to buy rare resources/sell what you found. 4, Find some npcs to communicate. 5, Fight some offensive creatures/guardians. 6, Gather the energy for jumping to another galaxy...

The graphic is ok, but unoptimized, even with my new pc i can still feel laggy during the playing. Music is not bad, it corresponds to the lonely atmosphere but nothing outstanding if u ask. Upgrade is unclear, you have no idea what are the costs of the future upgrades because you only get access to the new technology by chance. Resources management has the same issue, so many resources to collect from the beginning but only a few of them are needed.

Overall, NMS is definitely far from a attractive game. Considering its high price, there are many better walking simulators than this one. I personally don't recommand this game even it is on sale.
