So, I did a bit of searching around. Apparently quite a few people are able to run the game on a Macbook Pro and get good results running in Bootcamp. By good, I mean "playable." I.e. don't use retina resolutions, probably set everything to low, and reduce expectations. Again, that's fine... as long as it works. So, I think I may fork over the bucks and get a W10 license and just go that way... costs a bit more... but seriously, such is life. ;-)
