Well even if it's a small number, which honestly I'd be suprised if it were on the scale of San Andreas, because after all this is a handheld, I honestly could have lived without changing my clothes on that scale in San Andreas. Basically all I'd need in LCS:
A casual outfit
A suit/rich outfit
A few unique ones
But I could live with the first 2.
Oh and JACK25 ... Umm I'd say it's gonna take up as much memory as it can, if you mean to run it that is. Save file will prolly be normal size, if it were over a meg and a half I'd be suprised. And well you probably are aware of how the MP3 player works, yes it's "bad", but don't think this means the stations are short/redundant just because you have to choose between mp3 or normal as opposed to how it is on the computer. I'm sure Rockstar has something good for us.
