Oh I see, same here I played it for the first time in 2017... at that time I didn't appreciate it enough since I thought campaign missions were all there is to do until I started diving into the challenges and what not... that's where the meat of the fun is in these games!

Nah, all episodes were released by the time I started playing the game.

yeahhh you gotta be patient and let the strategy come to ya haha!
also did you get a chance to play the game when it came out in episodes and you'd wait for the next one...

Hahha, I remember some of those season 1 escalations really had me trying for hours.
