Video Game Abilists

Okay, why do no video games have this person selling "The Mystic Breathing Potion" to help with your asthma or COPD?  For that matter why do video games typically not depict persons with physical limitations?  Is it too much for say an apocalyptic story-line to have a war vet that is missing a leg or an arm?  Maybe a diabetic managed to survive the apocalypse?  I know we still have the ongoing debate about female presenting characters being under-dressed and we are starting to see more characters that are heavier, but where do the deaf people fit in?  The savants?

How much more complex could a sires of challenges be if the chosen character was in a powered wheel chair?  First there has to be room for it to fit.  There would have to be random electric outlets to plug into possibly putting you in bad situations.  You could have upgrades via mechanics in the game like tracks instead of wheels.  Maybe an upgrade for a mini-gun turret?

Basically in my experience game characters are very fit, very able, very nimble, why do we not see an 88 year old warrior with all the limitations that typically come with age like decreased mobility, the need to pee more often, short term memory issues, etc?  Imagine not only a health bar but a need to pee counter that could cause you to slow reactions in battle because you're afraid of wetting yourself or at a certain level of urgency the character begins doing a pee-pee dance.

Just adding these characters as a playable difficulty option every-time you complete the game could have people playing the game more.  So say you complete the game in normal mode, difficulty increase could be "Asthmatic mode" from there "88 year old mode" then "Power chair mode" or even let people choose that mode at start.  The point here is that different players could sort of play as themselves, you could keep eyeballs in the game longer, it becomes less about look at how fast I can play this and more "how do I solve this."
