One day the servers will close and the game will be gone from everyone's computers. It is not like other games where even 30 years later you can still play it. All the money you spend on it is fleeting and so is the ranks you get and all the achievements. In 20 years what will we be looking back at? it is not like Skyrim that will always be with you forever. So go and buy Skyrim, play Skyrim, it will never abandon you.
