What size is this that hte game becomes magically unplayable? Doko has yet to find that limit the original guess of 5mb was not it, 8mb came and gone. is it more than 10 or 12?
My game started to give problems once I reached 6Mb, and while a range of game save sizes are stated on this forum (from > 6mb), this does not diminish the problem, in fact it means what PS3 gamers are facing is complex (and potentially universal). Just because you haven't experienced it yet, does not mean that you won't.
Incidentally, I was also sceptical at first, and then my game stuttered and lagged. It's only a matter of time Doko.
