I play on S7 as JaKa, I have been playing this game since December of 2013.
The game continues to add content and events.. there was a world cup event, where players wagered on the real world tourney and additional upgrade options where increased for high level players (Aegis). Free players are currently working towards a clothing option.
I notice as the game ages, content and upgrade material become easier to get, enabling moderate and free players to catch the top level players.
I have played many F2P games.. this has been the longest I have stayed with a game. I will not rate this game as a ten however.. The free players are so demanding and sassy.. because they are cared for and receive benefits for nothing... they become like attention demanding kids... gross.. you can pick them out in these reviews... Easy to identify... low rating.. self absorbed crying.. yet keep playing the game..
