Chickenator.108: "Might and Magic X: Legacy" - MAC version works without Steam and without uPlay. Just move the game out of the steamapps folder and start it by double clicking the app. Steam can even be unistalled.
There is not even a login request for a uPlay account in that version of the game (unlike R.U.S.E., grumble, grumble).
Whoa, there's a login request for RUSE? That's interesting, since the store page doesn't list Uplay as a third-party DRM.
Also, yeah, it's pretty cool that Mac doesn't have Uplay. It DOES have the old Ubisoft launcher, though, as evidenced by Assassin's Creed II, so it's cool that Might & Magic doesn't use it. I've added it to the list.
