The game starts off like any RTS where you have to find and build up resources and resource collection. This doesn't bother me in the least. Then you have to build up your buildings so you can generate an army. You have your air strip, your barracks, and your tank depot. So it has all your standard features of an RTS and its not too spectacular.
There is one "new" thing in RUSE that separates it from the rest of the RTS squad out there. It has espionage modes which allow you to initiate radio silence, reverse communication channels so that your enemy thinks your tanks are planes and your planes are tanks. But here is the major problem. They only affect one area of the map at a time. You'd think that something like "Hey assholes, stop using the radio for a few minutes" would be map wide. Apparently its only in one region. Same with the rest of the RUSE abilities. Its like they have tunnel vision and they can only use it on their friends of friend, but not their real friends, more like the friends they made at the office Christmas party last year but haven't seen since because they work in another division. Yeah, that trailed on, I'm sorry, and I'm glad were past that.
Here's an idea, why not make radio silence cover all units instead of one region? Sure the regional restrictions when you're deploying dummy units is fine, but come on, regional restriction on swapping radio frequencies and radio silence? That just seems like lazy coding to me.
Additionally there isn't much fun in this game. If you like the Total War series, but think the game moves too fast for you, and want a game thats more like playing RISK with a time limit, then feel free to play RUSE.
All in all, I wouldn't call RUSE a fun game. Its more like an attempt at fun by a simulator that has been dusted off and put into production because the military didn't deem it fit for their usage. Its pretty much RISK online, but is much more about tactics and strategy than it is about swarming your opponents. If you like RUSE, you should go out and get friends and give RISK a try. Its a lot more fun than RUSE, especially when combined with beer and people with a good sense of humor.
