Every game has time gated content. Any game you buy nowadays comes with dlc you pay for later on included right on the very disc. Its simply not accessible until the developer deems it is. Any mmo has new content they release at certain times. Paid or otherwise. If they released everything on day one, they'd have no playerbase within a month because everyone would be done and bored. Any mmo out there wow, eso, swtor, etc all come with patches that unlock content at specific times. Its done for a reason and it keeps people playing. This is nothing new to gaming.
