How many times are people going to fall for the "Not enough content for 60 bucks" meme. First Splatoon, then Overwatch and Now ARMS are all going to be successes because they learned it's not DLC that's bad it's paying for elements that should already be in the game that's bad.
If the game looks fun to you then it doesn't matter if you spend 60 on it today or months from now when the game gets more content.
These days they intentionally cut content to nickel and dime people. In 2005 they came out with FULL games on day one and added a big expansion pack later with unique content.
