Is there more than one definition? If Nintendo created it with the intention of releasing it, it was "meant to be obtained" and "intended" to be obtained, and thus should be allowed on simulators. Of course this is impossible to prove until they actually release it, but it's a safe bet to say that if they referenced it several times in-game, bothered to create sprites, a movepool, ability, and stats, it was their intention to release it.
Besides, (and this is a big point), what's the harm in using it? No one is being placed at a disadvantage here.
No, there's one definition, but I defy anyone to tell me what Nintendo does and does not intend for us to do with the games they make. You hit the only read nail in the wooden board that is this "debate" on the head—it is impossible to prove this until they release it (if they do), so the only thing we can do and should do, as far as simulating competitive play as accurate as possible, is wait.
And yes, I realize there's no harm in using it. The real issue is ensuring both players are playing on a level playing field and are on the same page before the battle. That is why Obi made this thread, to clear up that point—and the clause has been implemented in Shoddy to see to that. Before, it was more difficult to be on the same page with every single opponent you played on Shoddy, and now it's much easier. I don't feel like signing on to verify if there's a DT clause and a OHKO clause on Shoddy like there is on NetBattle, but it's the same idea.
Well, my personal definition is: Pokemon, items and features currently available through normal usage of the game, ie, things that can be assumed to be a deliberately included part of the game. Things are are only obtainable through glitches or 3rd party devices are currently unintended until there is an official release of them, even if they are common practice and considered acceptable by the majority of the community.
Of course, there are some things that may not be intended and are accessible through the course of normal gameplay but there has to be some assumptions made unless Game Freak feels the urge to make a list of every last thing that they intended to have available in D/P.
You see how, while trying to define "intention" in the scope of this argument, you are forced to try to define "normal", and in that definition, you use the word "assume"? That's why I wished you guys luck, because it is pretty much impossible to say without a shadow of a doubt to say what Nintendo intends to do.
You then go on to state "common practice", so please consider this question: Do you think that Game Freak intended for us to save before encountering every legendary and uber, and turn the game off if what we may catch isn't statistically (or even aesthetically) to our liking?
And Kijin, you're going to have to chill out in this thread, especially since you've stated more than once that it's a "circlejerk" in which nobody has any business still posting.
