This is not a finished product. If it's advertised as so, it's a lie. It's very much unpolished - you can, for example, zoom into the ground, revealing hidden units or objects (NOTE: This issue has been corrected in the recent patches). It has potential to be a great game, but there are a few things you should consider before buying. First of all, this game came from Kickstarter, where it received more than 1.5 million dollars to be produced. Anyone who plays it, though, wouldn't say that it feels like a "1.5 million game". There are much better games in the market produced with less money. I was a kickstarter backer and I feel kind of deceived, because it doesn't look like all the money we gave to the developers was well spent in producing the great game that was promised.
Voice acting is bad, the story is bad, gameplay is decent at the very best, and the main characters are very poorly animated. I don't know how they decided that "animate the wind blowing the character's clothes" was more important than "ANIMATE THE MAIN CHARACTERS FACES WHILE SPEAKING". Really, in all dialogues what you get is a blunt face staring at emptiness, while a voice-over is played - done by someone who clearly isn't a native English speaker. Hell, I'm not even english or american and I can tell the voice acting is bad and done by someone who's not completely fluent.
Bottomline: if you're a fan of tactical turn based games like me, wait for a Steam Sale and get it; however, you should also be open-minded and have a lot of patience to overcome Warmachine's current shortcomings. If you're not a die-hard fan of the genre, don't even bother.
It will also depend on how developers will fix/improve this game with patches over time. What I'm doing, and suggest anyone who bought it to do, is waiting 6 months or so until this game GETS FINISHED.
