Currently for me, EF by a wide margin, then CSME followed by WF. Haven't played PBEM RS in a long time but have to agree with Cole that the RS graphics carry the day when compared to EF/WF. Always been an WWII East Front gamer first even way back in my board war gaming days in the 70's and 80's.
A shameless plug for CSME if I may. Its a pretty cool game with the new desert and night graphics and by all means the new recon feature! With the newer weapon systems since WWII it can be very lethal for your opponent or you so be advised. "First Shot Principle" definitely applies as does "Concentration if Force" IMO. Trying to stay alive on the modern battlefield takes some thoughtful planning and skillful execution. The bad guys guns are just as bad as yours!
I like the direction the development team went with CSME. Patiently waiting to see what CS'Nam and EFIII look like.
Good luck Rebel and good to see you back!
