Thanks for the links,
Your Welcome.
I started digging more to find out about S.T.A. and it looks like 1.2 is free for all but the newest version (v3.0?) is behind a pay wall. What's up with that?
Yes it is. Only version 1.2 is free, you can make an optional donation (To be able to have STA mod in development and keep this forum up)
And there is difference between versions :
STA1.2 it is the most stable, but no longer supported mod. It is a standard for any new user's patches and mods. It is a free for d/l.
STA2.2 it is beta mod, which is available only via donation. It has more new Campaigns, missions and tanks than STA1.2.
STA3.x it is advanced mod with a new features (improved AI, tracks repairing etc), more tanks and more Campaigns/missions to compare with STA1.2 and STA2.3. It has alpha status and available only via donation.
For more information, see their forum. I think... I helped a little
Best regards
Andrew
