inFamous doesn't make the top 5??? Hmmm... I'm tempted to delete you off my friend list for this madness!!

Damn, I only have five of those... But at least four of them are on my purchase list!

Just my personal opinion obviously:

#20 - No
#19 - Have not played it yet but does not look like a must have.
#18 - Yes
#17 - Yes
#16 - Yes
#15 - No but everyone need a 2010 sports game (Madden excluded :P)
#14 - No
#13 - No
#12 - No
#11 - No,unless you're a Final Fantasy fanboy like me lol.
#10 - No
#9 - Yes
#8 - Yes
#7 - Yes
#6 - No
#5 - No
#4 - No,worst game in my PS3 collection.
#3 - No,first because its not really a game and second because all you need to know is the story so a rent will do.
#2 and #1 - I already knew what was coming: Yes and Yes.

Nice list though i dont agree with some but thats just cause of my own personal taste.

I applaud your list,and the mentions were good also.I think Resistance 1 would have been nice to mention,it was the first shooter on PS3 and at the time of it's release the largest online FPS
