NO, you cannot start players with a set Tier of Civ/Mil/Fleet research done in any way, shape, or form.
Yes, I have some wonderful templates for 7DS 2.0 (Soon™) that allow a mapper to create a homeplanet with starting stuff like a capital fleet, mixed fleet (caps + cruisers + frigs), cruiser and/or frigate wings, labs, industry, tactical structures, advanced tactical structures (like planetary shield generators or nanoweapon jammers) or even cannons. All easily placed from within GalaxyForge.
However, sadly, SINS doesn't let you adjust things per the "WISH" I have in the first post. Would be nice, wouldn't it? Maybe for SINS 2.
