I'm two years in with a cheap laptop desk from Amazon to hold my Laptop and two clamp-on fans, works fine for me.

I did, thanks for asking! After doing a lot of thrifting and sale hunting, I ended up grabbing Forza Horizon 1 for the 360, a refurbished Thrustmaster 458 wheel, aaaand.....a cheap laptop computer desk. That last one definitely wasn't ideal compared to specialized racing mounts, but I was doing my best to keep prices down, and it honestly worked a lot better than I expected. Turning it around backwards ended up being very comfortable for the wheel and pedals, so long as you're wary of the center bar. The only thing I want to do now is weigh it down a bit so its a little more tolerant of turns on the wheel. Honestly I want to weigh the pedals down too, as they tended to move around on the carpet. All in all though, the whole setup worked pretty damn well for what we paid for it! As for Forza Horizon, it was EXACTLY what I was looking for. Better than I could have hoped for, in fact! Before bringing it to my grandfather I tweaked the settings to make it as userfriendly as I could. Got through the tutorial, made the controls as forgiving as possible, disabled the music, unlocked a few classic cars, etc. I also set the xbox up so it would boot directly to the game, which ought to help a lot. So far my mother and I have gotten him to play once, and he had an absolute blast doing so! It really warmed my heart seeing him laugh and smile as he played the game. He was just moved into the memory care unit of the retirement campus, so we are hoping we can bring the whole setup into his new living space so it can be a permanent fixture in his life. Should be attempting this in the next few months; I'm both excited and nervous to see if I can convince his aides to help make it a regular part of his day!
