In the end Red Alert 3 has some good and bad things. It isn't the best RTS out there, it's got some issues with pathfinding and the additional features of the units need too much micro-management in order to be really of use. Also it seems the slower economy and easier AI are compromises to allow easier play on consoles which doesn't help the PC version at all and rather turn it into a cartoon version of itself than become better than its predecessor, RA2.
On the other hand, gamers get the typically cheezy storyline that's brought to life by an all-star cast doing an excellent job, co-op gameplay that's a first in RTS gaming and plenty of missions and multiplayer maps to keep you busy for quite some time.
Red Alert 3 doesn't set a new standard but it does offer plenty of fun gameplay to keep you busy for quite some time.
* Co-op campaigns are great
* Easy difficulty a compromise towards consoles?
* Co-op invite system is clumsy
