With the news that you in fact can walk diagonally in the new X&Y games, why is everybody so excited? I mean, you've been able to do that in the Mystery Dungeon series for years.
The issue of walking diagonally has never been that exciting to me. I'm pretty indifferent about it.
I guess since it is the first time in the main series, it's somewhat exciting to most people.
Because X & Y are main series games, and the general masses will play them, as opposed to the Mystery Dungeon series, which doesn't appeal to every fan of Pokémon; at least, not to me. Pokémon Ranger (and Blue Rescue Team, I understand), a side-series I love, used the touch-screen before Diamond and Pearl, but it was still an amazing feature to have in those games.
Whatever feature it is, whether it was featured in a side-game or not, it will be exciting to have in a main series game, because those are the ones that draw all the attention, and those are the ones that people will use to judge the entire franchise of Pokémon.
