I just got a PS2 for Christmas and need a memory card.Do they hold more than one game?

Can Memory cards hold more than one game ?
Memory cards hold as many games as their memory provides. The memory card will save on it however much you play. For example, if you use up 10 megabytes on 1 game, and your memory card supports 20 megabytes, you can play that game until all those 20 megabytes are full. Either that or : Lets say you play Dark Alliance, and use up 15 of your 20 megabytes, then you use 5 on some other game, you will not be able to save again until you delete something from your memory card. (i used a small scale for this, i have no idea how much the average memory card holds, or how much memory every PS2 block is..)
Reply:Yes they hold games in blocks. Depends on the games, and the size of the card, but mine tends to hold at least three at a time. Just get one to start and get more if you need them.
