For me it's more like 30 to 40 PS2 games as opposed to 15, and I already own about 40 on top of that. Lol I know people have more, that's just the point I was trying to make.

Personally I know it's not possible but I really wish you could transfer data from PS1 memory cards to PS2 cards because the PS1 memory cards I use can only hold data from about 5 or 6 PS1 games, as opposed to the standard PS2 memory card which can hold a dozen or more, well with the exception of some earlier PS2 games which take up about 1/4 or more of a card's space. Oh well.
