For only are missing:
- Asset indexing (it is a pain in the [mod edit] search for anything)
- More than an grass in the paint floor Tool
- in Texture paint tool, All textures have the same fade and overlap equal to texture number 1
- Some weather effects
- An efficient road-building tool as it exists in S2engineHD
- leave zombies stupid as they are
- but make military AI even better bit
and that's it
Ahhhhh the most important of all, a multiplayer independent, without the need to have to buy the development GG engine, maybe buy an executable, a steam account something like this
these things solved and GG gets better than Unreal, ehehe
well not unreal engine but some of the ones in the market that are a big shit and sell like if they are better than GG
