I'd say a game with a lot of legs is an unbundled game that manages to see LTD sales in excess of 10 times it's opening.
Wii Play, Fit, Carnival games, and Game Party would all be great examples of it on the Wii.
The X360 has had a few like that recently - especially their Singstar (a very leggy game) ripoff 'Lips'.
Back from the dead, I'm afraid.
