I can say that I was pleasently surprised by how fun I found this game and how much time I have spent on this game (Second most played game) when you are going through and unlocking all of the planets you are always having something to do to unlock the next planet or to get your next planet. I also like that you can do so much with the game with out having to worry about the prime aspect all that much. The only thing that I don't really like about this game is that when you do the missions for the planet junctions some of them are a bit vague and you do have to occasionally look up on how to get through it which takes time out of game play, and it is also the same with actually going into the junction to defeat the warframe that is garding it when you don't know what your doing you have to look at how other people have done it to be able to do it. Other bar that the game is great
