Picked up the PS2 bundle at Costco last night for $265. Included the PS2, Jak and Daxter, extra controller, and one memory card. Thought it was a good deal. Anyway, I had a question about the PS2 memory cards. Please keep in mind that I haven't had any game consoles since SNES and haven't played much video games in years so please bare with me. How many PS2 memory cards do I need? I won't need one for every game will I? Also, does it matter which slot I have it in? In other words, will I be able to use both slots at the same time to get 16MB of memory? The instruction guide didn't really explain the memory cards very clearly. So how many will I need, maybe 1 per every 3-4 games? Thanks!
