To be clear , the J man is talking about what each console brought to the table so no "PS3 is closest to the PS2 because sony made it"
Similarities:
1 year head start
Failure Rate
More third party exclusives than the rest
More AAA exclusives than the rest (based on metacritics)
Less features than the competition
External Memory Card/HDD
Differences:
PS2 was the weakest of its gen technically while the 360 isnt
PS2 was a god compared to the 360 in both First party/Third Party exclusives
Online play was not a big selling feature of the PS2 while with the 360 is.
N64 is the ONLY console of the fifth generation!!!
