Once upon a time, games were about reaching the end of the stage, stomp some critters, sometimes with a princess in the end.

Now every game has it's own in-game leveling system apart from the game itself. There is always something demanding your attention: one more level, one more achievement, one more tier of digital glory to be conquered and forgotten the next minute.

I'm glad I'm not the completionist kind of guy, because would be frustating to get 100% of everything on every game out there.
