Just got this PS2 for my daughter and I'm addicted to this thing. It's great! It's hooked up to my HT system and I love it. I've already taken over her gameboy advance SP. Thank God for her early bedtime. Here's where I need help: Do I need a separate memory card for each game? I have the first Prince of Persia and it's great, but if my daughter puts in a crash game or something, it asks if I want to format the memory card to save her game. I know this will erase my old game. So what's the deal here? I new card for each game? Another question: Are there places to get these games for less- they are pricey! One more: What are the hot games for kids- she's nine and I'm 38 (a bit of an older kid). Thanks in advance for your help.
