I'm just starting to get into this, and it's a lot of fun already but so confusing for an oldie from the age of UT/Q3A Deathmatches, mostly due to the F2P nature making me worried about every choice I make (I had to pause and switch back to my PC to look up which warframe to pick for starting). Between that and multiple currencies and weapons mastery, helper guys, items that seem to be one-time use... I've got an uphill road to climb figuring this stuff out! I don't mind spending money on things here and there but I also don't want to do the whole "buy this neat sounding item/warframe, find out I get it for free as a drop in the next mission" thing. Still I'm loving the gameplay so far, so much better than the last F2P TPS I played (the one that the guys who did the new Tribes: Ascend did before that).
Next time I get time to play I might have to set something up with some fellow GAFers to help beat the n00b out of me.
