around 250 for me,i am an easy customer on this kind of games: if i like them enough i would willingly spend money on them to get what got my attention,but i also got the rule to never spend money on more the one game at the same time(if i spend money on fkg,i wont do it for lol).
i know i am probably wasting money,but i also think that everyone can do whatever they want in the end.
