Realistically is more or less encoded “without ending the collusion between Democrats and Republicans.” As it stands, the system is designed to reinforce their duopolistic control… and their followers, more concerned with winning than with fundamental human rights, allow it to continue.
I’ve played and DMed all but 4E, and 5E is easily the most accessible version I’ve played. I agree, though; 5E with some tweaks works very well as a video game. 3.5E, as much as I love it, can get incredibly complex very quickly. AD&D is, putting it kindly, a shitshow. The system is needlessly complex and convoluted.
