You didn't say that you can't understand why anyone would want it. Your first comment was "stupid game, 2 month life span at best!". How can you claim a game to be stupid and have a 2 month life span if you don't even know what the game involves? You are basing your opinion on next to no information.
I didn't rip in to you, i just pulled you up for being misinformed/ignorant of the facts.
I always pull people up for talking rubbish about something they know little about. Maybe next time you want to comment on a game that you have an unjustified disliking for, you will actually educate yourself on the product so you can make an informed decision. Then i'll listen to your opinion because it is valid.
So anyway, now you actually know a bit more about what the game involves, why exactly is it "stupid" and why will it only have a "2 month life span"?
Also, what is your problem if people want the game? Are you scared that casual gamers will take over "your hobby". It it certainly the mentality of some seasoned gamers.
To those that are buying the game, are you buying it for the fitness aspect, the mini-games (skiing looks like fun) or so you can have the board for future games?
EDIT: You think the pressure sensitive pad is mainly for press ups? It is not. It is used extensively to make sure you are doing the Yoga exercises correctly and is also used for the mini-games. Skiing, marble mania type thing and hula-hoops thing among others. You really need to go find out more about the game.
