I've played every faction and was very involved from the start. The game had a huge potential to be a great strategy, but it was never fully realized.
I would like to clarify, the game is COMPLETELY FREE! You get better stuff as you play with in-game currency. As in every other normal game. It is NOT a p2w. If you want to get stuff right away you can use real cash, but it is very unnecessary.
I've noticed that the community can vary depending on what faction you play, but they're mostly friendly. Also, you can make two characters of different nations, and once you complete the research tree on one character (fully level him up) you are rewarded with extra character slot so you can explore more of the game. And i have, as you can see by the hours i've put into it.
I've loved the game and the politics and the fanatics and the smart, intelligent conversations alongside the trolls, the spies, the traitors, the jingos and the crybabies. You play long enough, pay attention to world and faction chats and you get to see it all. I've laughed and cried with this game.
Now, you're probably wondering why I don't recommend the game? Let's see:
+Diverse 6 factions with a variety of units and playstyles.
+Responsive and helpful dev staff.
+Politics could sometimes be fun, if you're into that kinda stuff.
+A true f2p, you don't need to spend a penny to enjoy it.
+Beautiful icons with oil-painting feel to them.
-3D models are very basic and cube-y (you know how in Company of Heroes you can zoom in and see details like the soldier's shoelaces or facial expressions? Well, in MoW they look like minecraft faces.)
-Buggy, glitchy and annoying, the numerous issues are well known and they have still not been addressed.
-The game is very ugly even on ultra settings, which would have been something i can overlook for the gameplay - this game would've looked good maybe ten years ago.
-The gameplay gets boring and repetitive to the point of becoming an endless grindfest.
-No events or story line or anything to keep you coming back. There were some, but no more.
-No reason to hold territories whatsoever, no bonus or anything. (Soviet Australia, anyone?)
-Poorly matched pvp, being second is a serious handicap. so you lose.
-Master battles are screwed by the latest update (Oct 14, 2014) - The computer spams its best units early game, so you lose.
-Boring, monotonous battles - once you learn the layout of the few maps, every battle goes the exact same way.
-All the animations are very poorly done - an attacking unit gets side-skewed for attack, while the victim takes it stoically - he is undeserving of animation.
-The lack of money when developing this game becomes painfully evident when you hear the 2-3 tracks that pass for music and the absolutely horrendous voice acting.
-Most units have 1 rather unimaginative skill.
-No player skill tree, no customization, no upgrades of anything, no retainment of units, no unit experience.
Unless all these numerous issues have been dealt with, I wouldn't strongly recommend it. If you like war games try Company of Heroes. If you like the turn-based strategy get X-COM.
You can deffinitely try it and have some free fun, just don't say I didn't warn you!
