Let me start by saying that I HIGHLY recommend giving this game some of your time to try it out. I think that MOST people will get hooked and want to keep playing.

This game is a blast to play. I have really enjoyed the story (Which has more to come) so far. It is a Free to Play game like (as far as the the slots go) World of tanks or other slot driven games. So you will start of with a limited amount of slots for frames, primary weapons, side arms, archwings, and companions. To get more of those slots you will need to use premium currency that is bought with real money, or you can sell items you get in game to other players for that currency. Please remember that there is a lot of content in the game and the publisher has to earn money to continue to support the game and make more content. You really do not have to buy anything with your "Cash" in the game. Will buying stuff be faster to progress? Yes, it will be but it is not required to play. The first frames you get Can see you the the very end of what has been created so far.
Having said that I have enjoyed every minute i have spent in the game. To be totaly honest I regret not picking it up sooner than I did. At 750 hours I still have not done everything there is to do in the game and Am looking forward to the content that is planed for the future. To adress the grind that some have memtioned. Yes there is that. For a while when i first started playing it felt like i was either running out of credits or resources all the time. But as you progress you will find that you will have LOTS of the basic materials and only need to farm for some ot the rare items. It has never felt like a chore or a job to get this stuff for me. Frankly I have enjoyed the challenge that the game has put forth. Part of what has kept me hooked is that when you do start to get tired of doing something there is plenty of thing to go do instead. You can fish, Hunt (you do not kill the animals, you tranq them), mining (which has been improved), all in all a lot of content.
