I got about 2/3 through it. I could finish it in maybe an hour, but after checking the discussion thread, it just seems like PE2K and Serebii aren't interested in this, and that's kind of why I haven't really been jumping to get this done. If they're not interested, you really don't have an inter-forum RP. The only option left may just be to try getting two different forums instead of PE2K and Serebii, or release this on GTS+ as its own standalone RP, but that's your call. Personally, I don't think it's going to gather much interest like that, however. Not unless you revise the whole thing.
If you want to host it on GTS+ as a standard RP, I'll finish up the map, although I think it would be a good idea to revise the whole thing to address that. Or, if you want to try getting two other forums into it instead, that works alright too, as long as they show interest. Otherwise, if you really don't want to do that, I think it would just be best to let it go. To be honest, Serebii isn't big on major RPs, and PE2K is a dead stick.
Let me know what you plan on doing. But please, think this over carefully, I'd hate to spend another one to two hours making the map and then have the whole thing go to waste anyway. I've had that happen before and it's irritating.
