Just buy them mate, you won’t be disappointed
As others have said, it's not a game for the 'power gamer' or the history boffin. I would add that there is a lot of 'gotcha' style card play - forcing re-rolls, healing damage, weapon jams, for example - and if that style of game play frustrates you, you might not enjoy it as much.
FFOL rules = fun = money well spent.
Enough said.
