I think perhaps some programmers could make some little code
to have inventory also ?

Wand why not going further and making some basic :
- MMo style camera with zoom (you can go from third person
view ot FPS view)
- Power tree panel
- Basic RPG attributes level up system (the user spend earned
points to increase ( Strenght, Dexterity, Mana, Endurence )
- A little XP based system for heroes depending on level of
monsters
- A map displaying target zone for quest (like Follout Vegas
map system )

Well if anyone have ideas for improving or gooing further on the RPG template don't hesitate
