Same boat as you, tried SupCom (don't like), never tried WiC or CoH (not really into ww2/ww1 etc)
Did you play c&c3, there's nothing new, but atleast it ain't Generals lol..
I just got the expansion, Kane's Wrath, and it's pretty fun. You're seeing the events as CABAL/LEGION (CABAL from Tiberiun Sun/Firestorm), I just awoke my Cyborg army WOOOOOOOOO! The missions have been great, some being you playing the opposite side of what you did in C&C3 as GDI (actually help the GDI unknowingly, and start the Scrin invasion as Kane sorta planned).
