Recently Nintendo may have hinted at more DLC. There's some confusion over whether a briefing to investors was referring to DLC pack 2 or more content on the horizon. If it is the latter, I would welcome it mainly due to the quality and value of the previous packs. There are two routes this DLC could take, the first being a fleshed out battle mode and the second being more of the same. I'm gonna focus on the second option purely because I've personally never had that much fun in the battle mode, it always struck me as a little too random. Frankly if I wanted to play battle mode I'd play Twisted Metal.
With that said here's my personal wish list for a second season of DLC.
