Losing experience for loading a game is an extremely absurd idea.
Basically you would promote never loading the game, so you promote playing 24/7.
No gaming company should even attempt to promote this. Its bad enough that too many players are already doing this anyway.
Ideally you should take a pause after 2, at most 4 hours of gaming, and not game more than 8 hours on any given day, and thats assuming you are on vacation and dont have to do work or school.
Gaming companies are of course not in the business of educating gamers, but they should not introduce motivations for unhealthy gaming habits.
