This is quite the in-depth article on the topic, I might have to read through it a few times to digest it all.

One thing I was going to point out was I definitely see benefit to working on software changes where possible to save the cost of needing specialized equipment. The article does cover this

Holden cites Sea of Thieves’ addition of 'single stick' controls, where any swashbuckling and/or plundering can be performed using a single thumbstick

I was going to mention PSO2: NGS which has a single button to cast any spells based on what might be best for that situation (maybe one of the few things I liked about that game...). Definitely would like to see more of that. I also play FF14 and read a theory that the devs there consider button bloat a game feature, so whenever they simplify one skill (by making it a single button) they have to split another skill by making it multiple instead, which I find really unfortunate, I have a disabled friend who has trouble playing much due to the mass amount of skills.

And yea, definitely a good idea to donate to charity. SpecialEffect is listed which has been in the Yogscast Jingle Jam charity event at the end of the year. Assuming they have one this year and are taking part, might be a good idea to send some money their way or to other relevant charities for people who can do so
