I think maple story r for lil kids
EXAMPLE:

ive played all 3 of the games you mentioned

maplestory and other games may seem childish but when you first play it(especially with frends) its pretty fun/kool, but after a while you'll grow older and tired of that game and move on to another, there's no age limit to playing games

eh never played any of them, and yea shi is right, there really isnt a age limit, i mean some gamse a 80 year old and a 2 year old would like
