Hey dude, firstly go say thanks to your dad again for getting the ps3, a lot of ppl's dads dont just bring them home! He sounds like a really nice pops! Make sure u get an HD cable, sony are gay and dont give one free!
Anyways Ill list the games I'v bought with a good bad
God of War 3 - so good its the only game iv ever finished and played again on hardest difficulty! Problem is it's bad morel compus but your a loser if you care about that anyway, its a game, just have some fun =)
Madden 11 (returned) - This was the biggest disapointment of my life, I started madden 07 on pc and because it was so good learned all the rules and regulations in the NFL from the game even though it doesn't have a tutorial, Madden 11 on the other had doesn't even have a real become a superstar mode! I hate this game and it's put me off football which I love! People will call me stupid for this not liking this game but it just has too many little flaws to make it a complete game, its like they released it too early!
Demon Soul's (returned) - Being hard doesn't mean being fun. Also very slow start and its one of those, don't explain much rpg's which works but not when the game is this hard! Watch the zero punctuation review, its actually close to correct.

White knight chronicals - I've only kept this game because I support the team that designed it for try to make a game that is actually some what original and has a story with actually depth (as long as you look past the over the top character design!) Its game play is also fun if you like rpg's/adventures. Just get past the begining cause the story gets deeper the furthur you get into it.
Modern warfare 2 - Really good, I havent got black ops and don't know anything about it but I heard someone say it was the poor man's modern warfare 2! Lol, dont know if thats true but MW 2 is really fun and the champaign is so fun it made me think the game was really short but its not, can't wait to replay it!
Split second - Simply the best racing game I'v ever played. The cars are B E A utiful, the level designs are fun to play every time, if you have a bro or sis its really fun split screen. Its just a great game all round, I recommend this the most out of any game in the shops right now! And I dont even like racing games that much!
Red Dead Redemption - Its fun to be a cowboy! In this game thanks to the amazing environment, voice acting, weapons, horses, lasso's, characters and mood music you actually become one, its great!
Little big planet - As good as everyone says, just get it, its better played than explains, because its original. Just get it =) You'll see =)
Good luck with your ps3, treat it as part of your family, it can give you untold hours of fun =)
