Thanks for asking, and I hope that this project gets real, I'll support you.
First as for the type of game, I think we pretty much agree that it should be some kind of RPG.
About the gameplay, I loved the style of infinity engine's games some of you at Obsidian worked on, and I would love to play more of that kind.
The stuff that matter for me is :
- Party based, with control over all the characters
- Real time with active pause combat system.
- Tactical view with free camera.
- There should be other options than combat sometimes to beat an encounter: dialog, stealth, corruption,
