Kind of a tangent, but after playing the Pokken DX demo I've been thinking about how they could handle a sequel. The game is pretty unique in its fighting style, and while that's both a positive and negative since it has made it less friendly to jump into it also gives it a charm that no other fighting game has. I'd like to see that worked on further in a future game, and I feel making a new game would allow them to make the tweaks to the gameplay and content (like Single Player) needed to make it stronger.
Also, I want to see another sizeable set of Pokemon added to the roster. DX only added three (including DLC) on top of the Arcade four that were already created, so there wasn't as huge of a jump from where it was with the arcade version. There's so many Pokemon to add to the games with unique concepts to mess around with and it'd be exciting to see them just go wild with any of the options they chose. You could do so much with other Pokemon like making Lord Hydreigon use its three heads for different attacks and tactics, Feraligatr having a very aggressive playstyle influenced by its crocodile origins, or having Sirfetch'd dive into its lancemanship and make use of that large leek it carries at its side. It'd be fun to see where they could go with a bigger roster, and I hope TCPi gives them the chance to do it in the future.
