I agree.  I don't personally consider any game, as long as they're good and fun, to be "kiddy".   The Sonic Mega Collection gets plenty of play time from this 27 year old.
I really don't understand this whole "kiddy" thing anyway.  Face it, all video games, from Barbie to Grand Theft Auto are "kiddy".  They're games and it goes with the territory.  A far better criteria would be, "Is this game fun?" and "Do I enjoy it?".
