TC is Tactic Creator, the one with roles and duties (used usually for FM Classic). If playing the full game then use the other 451 (not LJM)What is 'TC' and which is which version? I downloaded both the 451 and I'm using the L-J-M 451 in the full game, is that right? On the triple tweak one it didn't have the player roles (DLP etc), just checking I'm using the right version, it got me promoted to prem with Harborough (my local team) so I assume it is the right one
