EB v0.7.4 (patch)

[Slider6977]

No RTW box version comes patched. All cds are the same version when they ship, and remain that way unless some catastrophic bugs occur in certain released games in which case the defected versions are usually recalled (which doesn't really matter, cause most people would have returned the game at that point anyway). Officially though, BI is 1.6, but that is because it was released that way, and the fixes that are meant for vanilla RTW that come pre-patched in BI were released as the 1.5 patch.

Not exactly. Standard R:TW comes unpatched, but if you install BI it will be patched to 1.3. There is also a gold edition which comes with BI and is already patched to 1.5 (and 1.6 for BI).
