Haha, yeah, FM's my weapon of choice too. I usually play the other two when I really want to indulge in some transfer fantasies that are either not achievable in FM, or don't make sense (like buying Roberto Carlos or van Nistelrooy for Wigan, or something), and maybe just to keep my memories fresh.
Just got tired and finished my FM save with AFC Wimbledon (tried to recreate the old gung ho Crazy Gang of the 90s, with
some success) and started a new one with Man Utd. Boy, the transfer kitty sure looks a lot bigger.
