@darthcobain17: When I was writing this review, I used 'human' instead of 'kid', but I saw a few comments referring to kid/squid so I changed it. It probably does refer to them as that in the manual, but I bet most people are referring to this commercial.
I hadn't seen the commercial until now; just checked it out on youtube. I think it's a good commercial but it is totally aimed at kids. Other people seem to hate the commercial but maybe that's the teenagers/adults complaining that it's too childish, so feel embarrassed to own the game.
I think it's just like other Nintendo games really. It's bright, colourful, fun, easy to learn, but difficult to master. I guess the Nintendo fans would have already decided to buy it before they see any form of advertising anyway (like me), so it probably makes sense to target the children.
