Buy this game ONLY if your are Star War fan, because there is no good "RTS" here.
At first glance SW was supposed to be this game, I saw again two camps of players, and I thought, wow(!) finally a controversial game with something new. I was wrong.
I did not realize who constitute these two camps. What I later understood (after I bought this game) is that the Star War fans give this game high score, and those who are RTS fans, but not a Star War fun, they give low marks. There is no novel and controversial element in the game at all!
As an RTS game, or let me even say as a GAME it lacks ... gameplay. Even the space battles, which most players say that they are good, are just eye catchy, with very little strategic element in it. You are just playing the game of the best fleet, and rock-scissors-paper game on large scale. Same with land battles.
The campaign and galactic conquest modes are somewhat similar to Total War games campaign, but done much worse. You can’t play “tratigically” there, because you can’t create defense at chock points because there are no chock points! The land and space battles are somewhat entertaining only first couple of times, after which you realize that there is little substance in them.
My conclusion: buy this game only if you are a SW fan and moderate RTS player (i.e. you are familiar what is RTS, but not specifically looking for stellar RTS gameplay here). If you are a hard-core RTS player, the chance is that you will not like this game even if you like Star Wars. You can easily deside for yourself by playing the demo. And if you do not specifically like SW, than STAY AWAY from this game, do not repeat my mistake!
