why don't they come out with a body building game. You could create your own character and modify it make it look like you. Just like in tiger woods PGA and other games. The game would focus on having to manage the day to day activity of your character. He could have like an apartment or house that you could go to and select when and what he eats. You could have a menu of all available food items available for him to eat and his body would respond to his diet. You would have full control over his food intake (carbs, fat, protein and what not)
You could also take him to the gym and work out on different exercises. Kinda like the boxing game on XBox. You could load up the plates and then have some type of agility requirement (like button configurations) to make the lift. The harder the lift, the more complex the button sequence. maybe by pressing the X and Y buttons repeatedly, or X, Y, Z LR?
You could control every aspect of his training and what not. To top it all off you could enter him into BB competitions. You would have different button configurations for different poses. The faster you pressed the buttons, the harder you flex.
There could also be a lifting store where you could buy supplements and lifting gear like belts, strap, chalk, clothing, etc., etc. just like in Tiger Woods PGA. Your player would progress as you bought better gear.....
With some work I think it could be a pretty cool fuvcking game.
