I haven't played this yet, and might not, but let me say this: your presentation, organization, and deliverance is ****ing incredible. You outlined exactly what you changed and made it easy to see. You even released the completed work soon after making the thread; rare to find these days. As a fan hack, this level of professionalism is extremely admirable. I can't stress this enough because I'm working on my own hack of B/W right now, and seeing this makes me want to continue all the more. The hack is essentially yours, but without the changes to the pokemon; I'm aiming for realistic difficulty.
tl;dr: Marry me.
