A Whole New World but Still No Money- I NEED HELP!!!

            Ok, so for a long time I went without playing videogames because I didn’t have the money to buy a new system (My going rate on the street corners was only a couple of bucks and I guess that was a bit cheap).  My only system was a PS2 which was ok but when everyone else is playing awesome, mind-blowing games it seems kinda lame to be playing games that I had beat 4 years earlier.  Most of the new games for PS2 are just the ugly cousins for PS3 or Xbox360 games that just didn’t do anything for my gamesterbation.  I need excellent games to gamesterbate to damnit! 

            As it turned out the gods smiled down on me and I was able to nab a PS3 for Christmas…thank you mom and dad.  Since I got the PS3 I am tortured with not having money to get new games.  I know I could rent them but for some reason I just don’t like having a time limit to gamesterbate.  I like to take it slow and soak it in.  The only games I have are Modern Warfare 2 and NHL 10.  This is because these are games that I could buy and play forever.  I’ll be playing NHL 10 for the next 5 years by just updating the rosters over and over and over again.  I have just sooo many games that I want to buy.  I want Bioshock 2 but I have to play Bioshock to keep things in order.  I want to play Assassins Creed 2 but I have to play the first one before that.  I’m a slave to sequential gamesterbation and it’s killing me.  I’m also concerned about replay value.  Any game that I buy will be beat within a few days and I need to know I can get more out of it than that first exposure.  That’s why I am coming to you Gamezombie nation.  I need to know what games would give me the best bang for my buck because there are just so many games I want but I only have enough money for a few of them.  I need your input prease!
