Happy and prosperous new year to all of you!

My idea is to place each tip in one category of each, e.g. the siege tower tip in "Medium" & "Military". That way the number of tips per combination stays relatively small and will hopefully make it easier to find specific tips or browse in an area that you're interested in. An index for all tips would be nice to have indeed, and some basic search functionality too. But that'll be more work.

The de-facto standard these days is GLTF.

I( wonder then, if we were so inclined, what format would we go to then? Why is Collada dropped? Its XML formatting seems really handy. 

All clear now? (it would be possible to run the game headlessly (with no rendering) and to force it to execute turns a quickly as it can)
