They're just trying to be friendly - so come and watch them sing and play. They're the young generation - and they've got something to say. Sounds kinda like "Ooo ook ook oo aaaah! Aaah! Aaaaaaaah!"
Pain, eh? Nature's way of saying 'this'll learn ya' when you do something stupid like fall on your keys in a nettle patch made of razor wire. With salt on it. Videogame-wise, however, there's virtually no chance a game will be able to physically cause you pain. Thankfully, there's a much more cathartic alternative - you get to inflict it instead.
