I really hate that I have to call this game terrible, but sadly I do. For me, it is almost unplayably bad, and I wish I had never wasted my money on it.
The gameplay mechanics are good; it is sometimes difficult to micromanage the orientation of platoons to keep them facing the enemy, and my recon helicopters have an annoying tendency to land whenever they're not actively moving, while I may want them to stay airborne to keep enemy units visible; the inability to set stances, and the rather awkward method of turning off individual weapons on individual units to keep control of who fires what, can be annoying, but I can generally get my units to do what I want. The graphics are fantastic, making each unit distinct and identifiable. The music fits the scene nicely, and the single player campaign storyline is nicely plausible.
So why do I call it terrible? Becuase of the awful, terrible, abysmal
AI. In single player, the game becomes almost unplayable, all thanks to the AI's absolute omniscience. Don't get me wrong, AIs have been able to see all the units on the field right back to the dawn of the RTS era, but it was generally not that big a deal. In Wargame, however, recon is a central element of any army's tactics. It requires careful attention to the type of recon vehicle, and equally careful scouting of suspected enemy strong points to avoid putting your recon vehicle in harms way. The AI does none of that. It just drops a full attack force directly on top of you, knowing exactly where all of your forces are at all times. it is even worse in the campaign, where the AI will face you with overwhelming numbers in every mission, often pre-positioned in ambush sites that you can take no advantage of. This severely reduces the tactics available, and ends up in a situation where the only way to make any sensible progress is by spamming the Quicksave key every time something doesn't go horribly wrong.
I play single player. I enjoy playing single player so I can take my time and explore my options. But this game makes single player a horrible, crippled experience that is more like a chore than a game. For your own sanity, Avoid at all costs.
