Did they provide some context: is this based on exclusives alone? overall software line up, what about what about hardware?
Either way I think the true unbiased, nostalgia free list would obviously read.
-PS2
-PS1
-PS3
-Xbox 360
In no specific order (ps2 probably first), These consoles easily have the most selection of games, genres and most flexible hardware for their time.
The N64 has way too small of a games library to be at number 4. Were there even RPGs on the system?
