Tbf, while daily-driving Firefox I do occasionally encounter websites (mostly web apps) that do not work on Firefox. But it's often a pretty simple fix, like sometimes I can get around it myself just through Dev Tools shenanigans.

I agree with you. It's been a while since I played a Mario Kart though. I got turned off by the "wiggle while drifting to get a boost" mechanic in Mario Kart DS (which I know is a fairly old game at this point). Even when I got good at it, it still felt really tedious to do all the time. But idk, maybe newer versions have a different mechanic now?

I like the idea of playing out the Byzantine generals problem in multiplayer or I guess with just another AI general too. Does Radio Commander have that element at all?

Not really. Planetside is an FPS with fluid combat. And it doesn't have MMORPG-style quests or environments. I think another way of saying the idea would be "Chivalry with persistent maps and an overworld tying them together in some way."
