I played a fair amount but more of a time filler than anything. F2P is F2P for me, I don't spend money on the game. There is a lot of stuff in it that I don't understand, I don't understand how to make new frames for example, I have parts but never get the items I need to make certain parts so never get an entire new Warframe. Only new one I've got is from my free in game currency that was given to me and 50% off token. Also, never had anyone to play with so most mission were done with randoms.
