DXRE - DirectX8 RPG Engine

Well, for quite a long time now, I have been working on an open-source DirectX8 Action/RPG Engine and starting to run low on features to add to it. So far, I need to add:

-Item/Inventory support
-Fighting/Leveling system
-Finish particle engine
-Animated tiles
-Remake Map Editor
-Chat system between PC/NPCs
-3D Sound

If I could get some ideas on what else to add, that'd be great. I also need help with finding bugs or anything that should be changed in the code. Any support is helpful =)
