Ok, so Mudkipblader, you got the fire dungeon. As for location, you can make it wherever you wish. (I still need to think exactly where mine will be, but I know it's under Lake Hyrule.) This is gonna be so fun. ^^ I choose Sapphire as the Water Temples Jem. Fire can choose between Ruby and Garnet, and the sand one could be Topaz or another yellow-orange-sandy colored gem. (Topaz is all I can think of right now. xP) We need a Forest Temple leader, and a hmm...what should the last of the normal world five be? (Then the last 4 we can all do together, we'll have Time of course, but those aren't places for gems and we'll have to come up with something else for Link to collect like he did the mirror in TP...he did collect a mirror right? Or was the Helmet second?)
I'll create enemies that you'll find in the water temple, including ways to beat them. And maybe I'll make a map. ^^ (Jeez, if Nintendo just looked here, that'd be so cool if our game became real. ^^)
