I try to play as best I can by true 5e rules.
Potions = Action
Jump is part of movement, not an extension, and you can't jump more than 10 feet unless you've got special characteristics
Cleric spells can only be used by clerics, same with mages
One surprise attack per person. No endless sniping
Etc., Etc., Etc.
It's frankly hard to do because I often have to look up different rules to refresh my memory, and enemies don't play by the rules. Also, I sometimes need to use jump just to pass through a space I should be able to pass through. Things like that.
