I don't have any problems with Maple Story going mainstream and advertising everywhere. It's only when their ads says stuff like: "Get away with murder!" or some other weird stuff that bothers me.
Trickster ads are worse, in my opinion, since they don't even make sense. Just a slide show of colors D;
As for old people playing games; my entire family--aunts, uncles, cousins, sisters, parents, are pretty game-oriented. We still pull out that Super Nintendo and finish DK1 or DK2 in one sitting every now and then, lol. Nothing wrong with playing games unless you're neglecting your responsibilities.
