The market demand trend in RTS games with a real life analogue has been towards *more* realism not less. The Starcraft and Warcraft settings can be wacky because they are so distant from any meaningful real world reference. EA should learn from the failure of the Age of Empires and Empire Earth franchises (not to mention C&C4). At the same time, franchises like the Total War and Company of Heroes are thriving because they provide more realism, often even at the cost of very interesting strategies or steeper learning curve. EA Games needs to grab this niche before someone else does with a Company of Heroes: Modern Warfare. EA has an edge with the CC Generals IP, but that won't last forever.
So, I would recommend that EA does NOT go for a cartoony/arcade game feel for CC Generals 2. I am very in favor of vehicle cover and smart infantry tactics. I would also recommend some genuinely urban maps with very restricted movement for tanks/heavy vehicles and cat-and-house battles among winding alleys and boobytrapped houses.
