The upgrade to the graphics and sounds is fantastic, even with having to have two copies of the game on board. The one thing I've found with this mod, however, is if you play the scenarios without the modified OOBs, you often get this "X" counter art. Looking at the units file, it looks like he separated the nationalities with some X boxes. The random unit generator for most OOBs, however, puts those Xs into play at times. Not all the time, but I've seen it in a handful of scenarios I've opened.
I actually found this anomaly after trying the counter art in AoTR. There it seemed to be a bigger issue at times, and with so many post-release scenarios for AoTR out there, being able to differentiate the summer from winter scenarios might be next to impossible. It might simply be better to have the terrain and troops updated, but not try to make the winter scenarios into a separate game, unless the X anomaly can be adjusted.
I fired off an EMAIL with a screen shot or two to Andrew, but it is something to consider while playing non-OOB adjusted scenarios or importing the unit art into AoTR, unless an update can eliminate this artifact.
