The duration of the game depends on the difficulty set, usually about 30-35 hours to try all the modes with objectives to complete, to try all the maps and mods available it takes many more, the game is very well done, nice and pleasant, the normal difficulty is more of a simple difficulty. The only negative note is that during the end of the turn, in the turn of neutral fighters the game freezes and must be restarted, this only happens to certain maps, otherwise excellent game, capped that it does not have a story.
The game starts well, but continuing you realize that you have thrown away money, few random scenes, the mechanics of the game are in favor of the enemy, there is no real randomness, the standard difficulty of the game is focused on enjoying the story, but once you get to the boss after the invasion you can't go on, so the difficulty is set badly, very serious error in a video game, in fact I uninstalled the game, it left me with a bitter taste in my mouth, because to continue I should waste time developing a winning strategy...... but if one wants to enjoy only the story??
