[Fanatical] Sid Meier’s Civilization® VI Anthologyy -91% (HL)

That's how I get these games :D bought both 4, 5 and 6 a few years after release, with DLCs

Civ isn't worth it without a few expansions on top of base game anyways is my experience with 5 and 6.

I am 100% waiting for some time on 7

I was just counting the years, as people at places were complaining about the release price about 7. It's quite high, but yeah, in a few years it plummets (and I think within a year or 1.5 the base game was bundled as well with 5 or 6)

It should work. There was a similar question regarding a deal from Aspyr in the past, where there only was mentioned Mac and Linux and it also worked on Windows, because there are no special keys for these versions.

EDIT: See here

Yes. You get all three platforms.
