"if you're telling a story you're not playing the game" while talking about the colaborative story telling roleplay game dungeons and dragons, also who even uses xp especially for roleplay moments that's like saying you'll pay in electrum holy larp
The bottom line is if you're telling a story, you're not playing the game.
Roleplay can and should be rewarded... With XP, bonuses or advantage, or in some other way.
It does not however change the game into a campfire tale.
