Massive space battles with customizable ships. Lots of fun, simple to get into, increased depth the longer you play. Good game.
While some people will always complain about the grind and the buy-to-win in a free-to-play game, the developers managed an interesting balance in those topics.
Don't get me wrong, there is some grind. But when compared to other free-to-play tittles, it's not that much.
As for the win-to-play that often puts off people in free to play games, I have to disagree with whoever thinks this about Star Conflict. Ships are divided into tiers, and each tier can have 2 to 4 ships of each class, with increasing effectiveness. Battles match-making is also divided into tiers. This means that when you get to rank 3 (the last of tier 1), if you are any good you will be owning battles like a boss. But as soon as you get to tier 2, a whole new world of ships, more effective, with better pilots, and more ships modules(skills), you will be like the little fish in the pond of sharks.... again. That is, untill you get the best ships in that tier as well. Same happends when you jump from tier 2 to 3, and from 3 to 4, and so on.
This leads to some people thinking they are dying because the other player has a premium ship.
While premium ships do have a very slight advantage in their stats, most of the time it's irrelevant. A good pilot is born from experience. Of course, premium ship owners are usually good pilots. Often only play with that ship and become very good with it.
But the slightly better stats will only make a slight difference in a 1 on 1, with 2 very good pilots. Any premium ship gets utterly destroyed with a simple 2 to 1. And lets face it:
If you and your team can't do a 2 to 1 in a 10 vs 10 battle, then you deserve to loose against him.
Finally, ships tend to get more effective as tiers go up, and pilots also become better with experience. This leads to the tactical side of the batlles to become more apparent as you go up, as well as taking longer to get decided.
The different ship classes are also well done, with each having it's own specific role.
In the end, and considering there is nothing of the kind in recent game releases, together with the competent work Gaijin did with Star Conflict, this game is mandatory to any spaceship combat fan.
Me? I was waiting for something like this since Colony Wars and Freelancer.
