This spreadsheet has all the attributes, capacities and assimilation effects for the minor factions based upon games played at 2/2/15 and later so all updates to the game are included. I play with all DLCs. I play with Aruiga mod which add capacities to some of the factions. I am 95% sure I have deleted those capacities from this spreadsheet. The attribute and assimilation effects are the same with and without the mod. I am not sure if the attributes/capacities are different for normal mode or any other mode. The types are color coded. The spreadsheet needs to be displayed in landscape mode to have it on one page.

I'm moving this thread to the Help & Tips section, where I think it's more likely to help people (there's already a thread compiling all unit types, I think it could benefit from having your data linked in it).
