I'm still deep in #43 also, but hopefully I'll still get to this one too...
The only question on the start for this one seems to be whether or not we move the worker to the mountain before settling. I almost never move a worker in the "wrong" direction to explore, but I think I will on this one. First spreadsheet draft shows that either way, we get 3 warriors before the settler on growth to size 3. Moving the worker directly to a BG would get a few more coins from earlier roads, but that's pretty insignificant if it turns out moving gets a food bonus.
Research will probably be Pottery first so I don't have to rely on trading for it. It should be effortless to get the Republic slingshot next on this level starting with Alphabet.
Musketeers not starting the GA doesn't sound bad since most likely knights will be all that are required (assuming we can reach the other continent pre-Astronomy) so open players also may have to find an alternate way to kick off the GA. The Great Lighthouse is often useful on 70% continents and satisfies commercial if we have a decent coastal city. Capture an industrious wonder before building the Great Lighthouse? Now I know why civ_steve took away Masonry for Predator....
