This is my personal score, coming from a traditional C&C background. This new gameplay style is a either hate it or love it kind of a deal. I personally don't like World in Conflict type style but I would love to read a review from someone that likes WiC game style for a different perspective.
I can't give a proper review for WiC as I haven't played much of it and I haven't played it in many many months. But one thing that I love about WiC is the no-frills RTS aspect of the game. I'm not even a RTS player yet I can handle and play WiC without any issue.
WiC is unique in its own way even though it uses a control-point style of battle rather than sending your army/fleet of units over to 1 or more enemy to destroy and conquer. All of your units are completely available to you depending on the class/role that you choose to play as. These come in fours and each one has a counter for the other: Support = long-range artillery + anti-air, Infantry = ground-pounder + anti-anything (or anti-armor specifically if chosen the anti-tank units), Armor = anti-infantry, infantry transports, Air = anti-anything-on-the-ground. Infantry and Armor are like bipolar opposites of each other and so are Air and Support. It's a complex mixture of rock-paper-scissors on a 4-way scale. While you are able to use the units specific to your class, you can call in units that are outside of that class, but for a price/premium. You're given X amount of spendable reinforcement points at first with additional points trickling in up to a max of Y points. (I think it's 4000 at first and 6000 max) When your unit is killed or destroyed, the point value of those units are recycled back into your reinforcement points (which then trickle slowly into spendable reinforcement points). So despite having a unit being killed off or destroyed, you can call it back up eventually or use it to call a different unit.
WiC has no base to defend, nor is there any economical infrastructure to build. It's a simple RTS game where people can jump in, play a round, and call it a day. I liked it because there is no infrastructure to build or manage and that's one of the things that puts me off when I look at other traditional RTS games (like C&C, Warcraft, or Company of Heroes). It kinda irritates me that I have to manage all that. If I wanted to do all that, perhaps it's better if I just play SimCity instead.
If C&C4 is trying to use a control-point style system, then there's nothing wrong with it. 5v5 multiplayer won't cut it though, as WiC can handle up to 8v8. Point system? Even a lowly ranked player in WiC can outmatch a highly ranked player. There's nothing to unlock in WiC nor is there any limitation on any units. Everything is available to you and units outside of your class/role can be purchased/used for extra. But while they can be purchased for extra, it's better to simply let others be able to deploy the unit that you need. The games all take place on a dedicated server and there are both ranked and unranked matches. I think there's also LAN capability but like I said, it's been a long time since. What C&C4 tries to do cannot topple what WiC has already accomplished. WiC appears to have better playability than what C&C4 appear to have.
