As for hacking: "A person who uses computers to gain unauthorized access to data." That's why. If someone is allowed to hack Pokemon into the game, then why don't we go on and hack different Pokemon into the Elite Four? They should too get other Generations. In fact, let's just re-hack everything! Different types for the Elite Four and Gyms! Re-do all the trainers! New citys anyone? (Note: this was obviously exaggerated.)
If you open the door to hacking, how is it fair that you, me, or anyone else gets to decide how far. If you can hack Pokemon, then why not TMs? Or trainers? Or items?
The game wasn't designed that way. The Elite Four wasn't designed with any Pokemon besides the one's that can be legitly obtained in mind. So it wouldn't be equal/fair, if we got new Pokemon but they didn't. We all know that one's experiance throughout the game will differ depending on their starter, or any other Pokemon as well.
I'm inclined to agree, honestly. I didn't want to have to intervene here as I thought maybe talking with other members and getting their opinions would change your mind, but this challenge is way too restricting. If this is an end of the game challenge, why is it SO important that things aren't hacked into the game? Why do you even care that much? Some people have no choice but to use emulators, and some don't know or don't have the time to do the emulator trading, so they hack in trade evolution Pokemon or version exclusives. But I just don't understand the purpose of this being so strict, and it's a big turn off. I've actually had other people complain to me about this challenge, and I kind of feel like now I shouldn't have approved it. Please lessen the reigns on this, or I'll lock it. I like to keep my challenges within their bounds too, but I'm not this uptight about it.
