All my yes. ^^ I don't mean 100% casual as in you can beat it with your first playthrough team - because the gym leaders will be challenging, and the champion will be the best amongst us, with a competitive team at his / her disposal. But I personally, don't want it to be 30 turns of switching Azumarills and Garchomps in and out of stealth rocks. Because seriously. There is NO instance of that, anywhere in any of the games, between gym leaders or elite 4, without going against other human opponents. I think if we just get the right spirt amongst the gym leaders, and keep sportsmanship and communication in our focus we should be alright. (not saying those pokemon, or things like entry hazards shouldn't be allowed. Just that we should be mindful about keeping a smidge of authenticity wedged between our pokeballs with this.)
Also - on what you said about the authentic gym leader / league feel- I think it's a great idea to discuss both challenger and leader teams openly. Helping each other out, suggesting tweaks to pokemon and team builds could really help some people step up their game. Maybe even get someone through the league who wouldn't have on their own, or had attempted to previously. And as long as the gym leaders are locked into one typing, their teams should be somewhat possible to document and share amongst challengers.
Hah - I wouldn't say I should be 'in charge'. I'm eager to help push this, since I love the idea and wanna participate though. :P And you haven't missed that much, only 3 pages or so. : , Primary issue right now is discussing logistics. Sim vs Games and all that.
Anywhoooo.
This weekend may be a good chance to spearhead getting this started. I'm gonna send out some PM and VM's right now, to hopefully get someone to involve themselves heavily with the Showdown half of the league. Volunteers would be great too though : , I know a lot of people in the thread already said they're backing the idea, but is anyone willing to take a spot helping to organize dat sim half?
