[Retopo Bridge Edge loops]

In Retopo I want to be able to select 2 edge loops and bridge them like in Blender.    otherwise it just tends to take too much time to connect 2 compatible edge loops.

Thanks

[HardSurface Workflow question(for games)]

Hi Guys

So I've made a hardsurface model(Sci-fi armor), it is composed of several parts converted to surfaces and now its time to retopo, texture and bake it: 

Do I have to merge all the parts first? (What if they are in surface mode)
Do I retopo each part individually?

I'm still learning this new workflow , My goal is to eventually make a model I could rig in Blender as a character.

If anyone could share their workflow towards creating hardsurface game assets that would help thanks.
