Yeah I do have it.
Been playing it for the past 1 year. Its a great game, a must have for fans of the movies!
From the RTS perspective, its kinda simple, the economy is a piece of cake to manage. The game focuses more on micro in battles, than on economy building, etc.
You bought it at the right time too, patch 1.03 is releasing next week, and believe me, its gonna be brilliant, considering the pros from Gamereplays have battletested it themselves(that includes me

).
You're better off waiting for patch 1.03, because in the current state of things, the game is very imbalanced. Mordor are way too overpowered, and Rohan is underpowered. Gondor turtling is horribly effective, while Isengard's pikes not only counter cavalry, but also infantry.
I recommend checking out this site for strats and stuff:

I'll play you when the patch releases!
p.s - Since I'm staff on gamereplays, I do already have a copy of the patch, I'll email it to ya if you like.
