Russ: Planetside2 looks very good on a limited playing session - not sure how far a player can go without making some in game purchase but I will play to level 15 and see how it goes. For a free to play game looks very solid.
Rocket league having server issues aghhh . This looks so fun and can't play :)
I played Planetside very briefly (not my kind of game) but from what I can remember free guns are among the best in the game so you can do quite a bit without paying.
As for the Rocket League, I managed to play a couple of games before the server problems started. The game is really fun, but it looks like I'm not very good at it:P
