>tfw ORAS will have the Battle Frontier from Emerald
>tfw the glorious Battle Factory will make a return

That alone is worth buying the game for. I sunk DAYS in Platinum's Battle Factory. The whole risk/reward system was so enticing, and if you ran into a really bullshit Pokemon who's overpowered, you could always add him to your team if you win the fight.

Only thing I'm not looking forward to are megas in the Battle Factory. Fuck that.
