Megas were at least nice.
We got new temporary evolutions (could be definitive, give'em numbers!) and with them some really cool designs.
Also Charizard was finally able to become a dragon-type, which was so damn long overdue haha.
Its was an instant win button that broke the game. In the game it was introduced, it was poorly implemented, as only 3 opponents you face in the entire campaign use megas. Not even the elite 4 used em.
It was used as gen 1 pandering, instead of giving pokemon who were overlooked and often out of the spotlight. Speaking of that, Banette deserved a full evolution, not a temporary super saiyan form.
Not a single gen 6 pokemon got a mega, except a damn mythical.
Bet with Intrinsic:
The Switch will outsell 3DS (based on VGchartz numbers), according to me, while Intrinsic thinks the opposite will hold true. One month avatar control for the loser's avatar.
