That someone better
People keep saying play other games. You need players for that, and my players don't want to learn another system, so I stretch the 5e core as much as I can to make it work for me, without making it not work for them.
I have no doubt that your players will not budge, no matter what.
So out pure of curiosity here:
5e is actually a deceptively decently complex game once you get in to the different classes with their associated little subsystems like sorcerers points...
but 5e is essentially Stat + Mod + d20 - compare to a target number (DC or AC etc..)
I do one-shots regularly with different systems, and the players have no issues picking things up inside 15min or so, then playing the game and picking up nuances as they go...
Do you know what it is specifically that keeps them from not wanting to learn another system? In my experience, the buy-in on the player side really isn't that heavy...
And again: I have no doubt that your players will not budge, no matter what.
I'm just morbidly curious to know what the reasoning behind that is...
