Alright I've just uploaded v1.3 of RotC - that is the most recent version of the mod I developed for EaW ONLY, in other words, it was the last version I completed before I made the mod compatible with Forces of Corruption. As a result it is a far inferior product, lacking the majority of the changes found in v4.1
Basically v4.1 is the premier version at the moment - it has the most content, is the most polished, and fits the most with what I originally wanted. BUT I know that some people only have EaW and not the expansion, so that's why I've uploaded v1.3
Please do not ask if I'm going to add the content from v4.1 into an EaW-only version, I won't do it. The reasons for this is that it has taken a long to get everything done; every version after v1.3 is based on FoC code; FoC gives the ability to have far greater flexibility, such as vehicles being able to transport infantry units. To put all of this into an EaW-only version would be very time-intensive, and really FoC isn't that expensive anymore.
The bottom line though is:
If you ONLY have EaW, you can only use v1.3, otherwise, please download v4.1
