The stuff is pretty doable. I've made a GUI Inventory already, which I can base all the other Full-screen systems on. Abilities are all complex, but easy to make. Terraining, I'm good at myself. I've gotten enough resources, except models, to be able to make this map. I do need some models and also some ideas for quests, NPCs and new areas.
Send me a PM to confirm if you wanna help.
