If there is one game this year where I can say the season pass will definitely be worth it for, it's Final Fantasy XV. Destructoid reports that on top of the 3 additional DLC expansions they are planning, online modes, and co-op, that they are considering adding even more stuff down the road! Of course, I'm going to take "considering" as an "if the game sells" kind of deal.
It's not as though Final Fantasy games loaded with DLC are not unheard of, but it is surprising how many promises Square Enix is making for a game that still has a month before it's even released! I can't wait to play it!
