Yeah like Torque 3D having some RTS or RPG Kits, i think Conitec should follow that way instead of trying to make templates and putting so much time , nothing before more than one or two years.
And users can put lot more time in them,an they can do lot more better graphics and HUD and all other stuff.

For example in Unity some things are coming :

Unity Roads toolkit

Unity RPG Toolkit

Unity Decal system

Weapon system

Just my advice for A8.

But in A8 like in A7 it's complicated to create easy to incorporate and remove plugins ?
In Unity , i'ev seen some code and it's easy to create a plugin caus you can access Unity interface easily in C# and create new panels and functions on top of default ones.
