there will always be people that eat away at the content quickly, Fallout 4 comes out and it has alot of content but you can bet your ass that there will be people that beat it the first week. nothing anyone can do not even timegate can stop someone from just eating content like sugar. if you made games to make them last awhile than I am sure COD story mode would take a few months to beat if they gated that because, people complain about how short COD story is. Or you can't prestige the first month of the game because they want you to enjoy the MP and see what weapons you like, get you know what you want in the game. Games would take months to beat if companies timegated stuff because people rush through games and beat it the first week.
