Certainly not the best in genre, but pretty entertaining nonetheless. Not a bad price at $10, although I would still wait to buy it on sale. $10 is worth it IMO....but still pushing it. I tend to have a higher tolerance for mediocre games than most, so others will probably only want to spend $5, at the most.
The story isn't real fantastic...or really even there at all after the short prolouge. You do get news casts after every mission for the first 20 turns or so....but they don't really add anything at all to the experience. Most of it doesn't even pertain to what you are doing in any way. (a major disaster in America, for instance, won't actually affect any missions you do in that same exact area) The parts that DO pertain to what you are actually doing....still don't affect the missions at all whatsoever. Basically just mentioning how well/poorly you're doing in the war. Not really sure why they even added this in the game, especially considering they eventually stop appearing.
The gameplay itself is where the game really shines (albeit, not very brightly. Especially not when compared to other games in the same genre). At the start of the main campaign, you choose to play as one of the three world powers (Russia, USA, or Europe) and then select a battalion to control (each with differing bonuses and unit preferences). Each mission consists of you deploying units and then using them to either capture uplinks, destroy "critical buildings", or destroy all hostile forces. Uplink missions can also be completed if you destroy all the hostiles, which ends up happening more often than capturing enough uplinks (especially towards the end of the game and/or when playing defense). After each success (or failure), you'll gain CR (credits) that can then be used to upgrade your troops for future battles. Units that survive the battle (even if they're defeated but successfully evacuate) will also gain ranks, which is mostly used to access the upgrades you purchase for that specific unit type.
There's not a lot of resource collecting in this game. The only "resources" you have are CP (command points) with only two ways to collect them. The first is the capture/upgrade uplinks, and the other method....is just to wait until they recharge by themselves. CP is used for deploying troops, and also for using your supports. Supports include Air Support (bombing), Electronic Warfare (disables enemy vehicles) and Force Recon (deploys troops on the battlefield that can't actually be controlled, but can still be useful for defending).
During most (not all) missions, you'll also gain a 4th support after the mission enters "defcon" phase (towards the end). The support is a WMD, and you can use it without spending any CP whatsoever! The bad news? You can only use it once before a long recharge time, which typically takes longer than finishing the mission. Another bad thing (or good, depending on the situation) is that the losing side gets dibs on using theirs first (although there are rare occasions when they actually won't). Another thing to keep in mind when using this WMD....is that you can hit your own troops with it as well.
When it comes to missions, the game is very open-ended. There will usually be 3 or more missions to choose from, and it's entirely up to the player which mission is undertaken that turn. Often after completing a mission, your country will win/lose OTHER missions as well. This can result in one mission's victory turning into 3 or 4 new territories! It can also result in gaining one territory in exchange for losing another....
While the voice commands are a great idea on paper, in practice they are absolutely HORRIBLE. The system is waaaaaaay too finicky to be of any use if you can't talk 100% perfectly in the way the game wants you to. You're better off just sticking to using the keyboard and mouse for everything.
Overall the game is a pretty enjoyable experience, but nowhere near the best option. I would really only recommend buying it if you're looking for a cheap RTS and don't mind the outdated graphics (the game is from 2009, after all. Wasn't really top-of-the-line back then, either). If you've got money to burn....spend it on the latest Sid Meier or Age of Empires game instead.
