The adverts seem pretty honest in their approach showing the benefits of a portable console. Not deception or misleading at all. Good honest advertising. It's not like women wearing sanitary towels jumping out of airplanes or guys having the latest luxury car and automatically having a beautiful wife/girlfriend.
Did feel the 1-2 switch advert was false advertising though even though I've never played it myself I've read people got bored of it pretty quickly and I've yet to hear much in the way of positive feedback about it yet the advert really overplays the entertainment value of it. Looking at Amazon a huge amount are disappointed with the product and this is very rare for a Nintendo title. So that to me was a poor product over marketed and would be a 'hate to say it' moment. However you can't really argue with the commercial success of the game, over a million sold and a tiny capacity cartridge. Huge profits for Nintendo but I don't think it gives Nintendo any kudos.
