I want to try this!
ONML gets a point because of its challenging levels and no repeats (though Wild 1 and Wicked 6 are similar in layout).
If the Playstation is the PS3 version, I'll take away two points because there aren't enough levels, and there aren't enough Lemmings styles (though the remix of the Lemmings music in the main menu is very nice). If it's the PS1 version, well, I've never played it, but I heard that the Special Levels aren't there, so it still loses the two points.
Lemmings: 6
ONML: 5 [+1]
Chronicles: 3
L3D: 3
Paintball: 4
Revolution: 3
Playstation: 2 [-2]
