No idea what seasons I've actually played but i know that this one is really fun, i like that you have to wait for more of the battle pass and content to come out, so you actually have to play over a long time period - which hasn't been an issue so far as its been really fun to play ! Not sure when they made the app a 'platform' , but i think it has really helped in making the game more accessable to people who dont just want to play battle royale.
The leveling system hasn't been difficult at all as im nearly lvl 200, but it's just fun to play at the moment
