I would vote for a Radious and DeI teams merging action. Thats a serious suggestion though. There is a lot of effort that is done two, three or even more times for the same thing, just in different mods. Just imagine: Remaking ALL the units of all factions is such a work... It takes a lot of personal and working time away and does basically the same (with minor differences only). I think both mods could benefit from each others work and create "preference sub mods" that affect things like Battle Mechanics, Campaign Mechanics and just things where visions, colors, flavors and preferences are not the same.
What I mean with preference sub mods is have the major mod or default mod being somewhere in between arcade and simulation (thats what CA should have implemented into the game anyway = CUSTOMIZATION OPTIONS) , hence pretty much balanced in all of its aspects but have preference sub mods ready for
1. things that just openly call for customization (e.g. 4, 12 or 24 turns per year / magic unit abilities turned on, or off / vanilla, bullgods or normals unit cards / etc.)
2. different flavors or visions concerning battle or campaign mechanics (fast arcade battle mechanics mod, slower realism battle mechanics mod / vanilla CAI or aggressive CAI)
3. things that are serious additions but do not necessarily need to be in the default mod (e.g. Hegemonia, TTT, Camera Mods, Graphic Enhancement Mods).
