Basically played this game the entire day - stopped for the two games of football.
My head is spinning. Now up to 67% and 100% a few of the side missions. I've just got the second BM. Way better than the first one with the upgraded stuff that comes with it.
Struggling to do the riddle stuff so i'm just going to complete the game and do the good side missions. The challenges are too much of a hassle to unlock imo so they'll be getting ignored as well.
