If you're interested in easy-to-join MP games and simple RT"S" action, then this is your game. Others beware.
Mostly the game boils down to a glitzy version of "Who can throw the most bang at the other guy the fastest?" The fact that units are relatively simple and can't be upgraded, etc., isn't necessarily bad, and certainly some of the units' special abilities DO have great use (like smoke cover). But that the single player AI pretty much just runs down predictable paths means that this becomes less of a strategy game and more of a puzzle ... it's not how do I best combine my units for an effective attack, but how do I get more fire power faster so I can hit my obvious AI staging areas? This point is made all the more clear when you consider that you are only allowed to control a certain number of units at a time and are, in fact, encouraged to throw units in the meat grinder as your reserve NEVER ends. It's like a shootout in which nobody ever runs out of ammo or really worries about getting hit.
Yes, that type of game simplifies things and makes for good action and visuals. It doesn't, however, make for a good strategy game. The nail in the coffin, for me, is the lack of a solid skirmish mode. What? Campaigns are almost always, in my view, little more than mega-tutorials in how to play the game. The Gamespot review also notes that the campaign is designed to get you into MP "tactics" ...but what if you don't want MP? Well, you're stuck. Perhaps this philosophy is behind the lackluster AI? Perhaps high-profile voice acting and good graphics sells better than bread and butter AI programming and single player options? I guess, but this just isn't my kind of game. To WiC's credit, it doesn't pretend to be the next great thing for the single player. Also to its credit, the campaign IS well done. It's just clear that once you finish the campaign, you'd better get busy with MP or put the game back on the shelf.
