Its one of those IOS games that managed to hook me for hours as opposed to a few minutes.
It feels repetitive, but i havent unlocked most of the missions to be sure. But as repetitive as it is, i doesnt seem to bore me as it should.
Economys good so far. It doesnt force you to resort to IAPs as everything can be earned with hard work.
The battlecruiser ship design is disappointing. It feels like a tugboat with guns with how stubby it is. Could use a bit of stretching to be longer and maybe be able to mount a few more guns. As it is now, the two other ships can mount more guns and looks more imposing. I also feel like destroyers do a better job at what battlecruisers are supposed to be good at.
Its not perfect, and has a lot of room for improvement. So for now, 4 stars.
