I won't buy this...as I heard CoH is much better, and I bought that already.
Nothing at all like CoH!
You'd be doing yourself a disservice by not buying this amazingly FRESH take on RTS.
RUSE is not an APM click-fest like StarCraft 2 or the like, I've seen plenty of "expert" RTS players (coming from WiC, CoH, SC or SupCom) getting their asses handed to themselves by "noob" RTS players because in RUSE it's *almost* SOLELY about strategy. TIMING is everything in RUSE. Since by default in RUSE you can see a light/heavy marker for every enemy unit and all bases are visible by default you MUST use your RUSE's wisely.
Do you show a fake attack on another front?
Do you camo-net your bases to hide them from view?
Do you build a fake airbase to make your opponent waste resources on anti-air when you don't even have a single plane?
Do you use "blitz" to speed up production and unit movement?
Do you scramble enemy intel to make all your "light" markers show as "heavy" and vice versa?
Do you use "radio silence" to hide all of your units?
Do you use "spy" to reveal all of his?
the list goes on......
of course these RUSE's are all TIMED (and can be applied by sector of the map)......so again.......timing is everything......running out of a RUSE at a critical moment may prove to be disasterous.
I can't praise this game enough! RUSE is a total GEM in the RTS genre and any real table-top grand strategy fan would be doing themselves a huge disservice in not picking this one up!
NOTE: This is not a game for the SC2 click-fest/APM kiddies......this is chess revisited!
