In keeping with the "first impressions thread," it's an excellent merging of lessons learned from CMSF and the classic detailed content of the CMv1 family. I do miss the detailed, clearly formatted in-game info available on a unit (the old "Info" dialog), but I can always search the web for those details.
One minor item of style which appears to have been ported directly from CMSF-- the fire mission call-in sounds like it's using the same mic sound effect as CMSF fire missions, even with the on-map mortars being called in verbally or visually, as in the Training scenario.
Lots of fun, can't wait to get into the full game. Keep up the good work.
