In this game, my PS3 depends constantly!

I used to play quite like Civilization II on the PlayStation. Since it was not quite up to date but it was time for a successor. By chance I saw the game here at Amazon and have 'the same order. Graphics and gameplay are very well done. However, if you have already set up a larger Civilization, the burden on the Prozi is so great that the PS3 here so approximately every 3 rounds (!) Hangs! The picture will freeze and then you can see the PS3 only shutdown and reboot again! This makes of course no more fun. So often have I already achieved and then it was all for nothing, because the console has hung. Now I save every 2-3 rounds! What shoud that? The game was very expensive! I hope at this, that there will be an update on what there can put things right! Because so annoys you so only still around! "The game, which Sid Meyer always wanted to do"? Yes, I hope not so, so each player herumärgert!
