Amazing! You're welcome. Yes it must've been around 2000, I was around 13-14 when I built Tiberian Sun Factory and then RA2 Factory.
To be honest I didn't play with mods much myself because I was consumed enough with the joy of building tools (such as for INI editing and voxels) and the websites, and connecting with the community and other site/tool builders. I did play the vanilla games a lot though.
I contacted the community manager at Westwood Studios and was granted the chance to visit once during a trip through Vegas. I remember him and others being very friendly, giving me a tour through the office, seeing the reality of the life of game testers, having some time with the Yuri's Revenge expansion before release, and being given some merch - a Dune II box, a C&C poster, which I still have in storage. Just to share some more of what I can recall from those days.
