They game has alot more to offer than mechs. Mechs are one aspect. In another series of games, there was occasionally a need to break into a locked container or room. Rather than try to simulate you actually having to break into a safe, they substituted some little game that challenged you via timing and coordination. It had nothing to do with the game and was annoying, but I found out if I used a drawing pad for one of the games, it made it a piece of cake.
I have several popups on my screen, most of which are annoying and get in the way, so I usually try to dismiss them as quickly as possible. It's especially annoying if I come into a battle and a game pops up at the same time, that won't go away by pressing ESC, but instead does the microsoft thing of asking if you are sure, of course if you just want it to go away, and ESC is set to close 1 window at a time, you keep pressing ESC, but in that UI, ESC means cancel. Similarly is where you make mods to something that won't save if battle starts: It **seems** that neither yes nor no works, but you have to press a third option, 'confirm' to really exit without saving. So all normal methods are broken, trapping you in the menu where you can't respond to the attack. Then you remember it some other key to get out, and press that key -- if the attacker was your level or higher, you might be dead before you over came your panic and were able to exit. It's designed to mess with you. So finally you get all those popups closed, and there isn't anything on your screen related to a quest letter, so what are you talking about again?
You know nothing of what a disability is. Whether or not it is physical, is irrelevant. It prevents you from being able to do what normal people do. The law doesn't differentiate between those who discriminate based on physical vs. mental disability. In fact for some areas disability isn't required at all. Differing levels of *access*, caused by race, creed, color, religion, medical issue, age and sex have all been successfully used to push cases involving different types of access and different types of discrimination. The meaning of discrimination has been expanded over the past century and applied to more areas. There is little to support some "narrow" interpretation. Whether or not those laws might apply to an online game isn't even the whole issue, but how it affects the perception of the company in the public eye.
I understand that some people have unreasonable advantages and some have unreasonable disadvantages and many are in between. I also understand that it isn't a black+white issue. The person who was able to compete in non-handicapped events with his augmented body -- should he then be able to turn around and compete in handicapped events as well? I wouldn't want to be someone deciding that case.
