I haven't even played the games yet and Gen VI is already better than previous gens. If this isn't the type of innovation that the Pokemon franchise needs to gather new fans and touch back to the old, then I don't know what is.
The question is, though: How "visible?" A vauge NPC telling you different phrases depending on how many EVs you've got? Bars like the contest stats? I hate to be a negative nacy, but the wording is fairly vague.
