RPG systems are far more comfortable than life.
Gain 1000 XP = Achieve Level 7 as a Warlock = Get two Attribute Points and a new selection of spells.
If only real life was that predictable! We’d all work harder, without any anxiety, because the goal is guaranteed by the system. Effort = Reward.
That sort of comfort is very attractive, both in RPGs and LitRPG. See you tomorrow!
