Short version: Don't believe reviews older than March 2015. The game is better, prettier, and more stable than ever before. It still might not be for everybody, but it's worth a look.
I've been playing since Early Access, but wanted to wait until the last of the Kickstarter DLC was released before writing a review. In the meantime, I've watched a nearly unplayably buggy game get lots of fixes and polish from the developers, and now I feel like it would be fair to give it a balanced review. APRIL 25, 2015
+Excellent character models and animations fully capture the look and feel of the Iron Kingdoms setting.
+Very deep core gameplay draws many concepts faithfully from its table top origins.
+Single player story is decent, written by game creator Matt Wilson, and has some fun missions.
+Each faction is very distinct, and has a good (not great) variety of models.
+Multiplayer is fun and intense. I've only dabbled, but I could get hooked.
+SP Skirmish mode is okay for testing teams or admiring art assets.
+Highly active and invovled development team communicates regularly with players.
* Some spell and engine effects are too shiny/intense for my taste.
* The balance between troops and warjacks has shifted quite a bit in favour of the former. Feels different from tabletop.
* No Man's Land single-player campaign leaves out two of the factions almost completely (3 if you count Mercs).
* Limited unit selection in early matches means not as much replay value for single player campaign.
* The user interface has been improving, but it takes up a lot of screen, and isn't the prettiest.
* Some of my favourite units aren't out yet, and I know I'll have to pay for them as DLC someday.
* Controls and camera are better than ever, but still take getting used to.
* There isn't a large enough player base to guarantee fast MP matchmaking yet.
- Core game features are not yet implemented
(no Hotseat, no Asynchronous MP, no painter, and only stupid-easy Skirmish difficulty)
- Single-player campaign has bad AI, and compensates with waves of suicidal dummies.
- Certain graphics configurations caused the game to crash frequently. I'm good now, but it was unplayable at times.
I recommend this game more than I ever could have before, especially to people who tried an early build and gave up because of the bugs and lack of polish. It is very playable, very fun, and worth coming back to. For new players, I would recommend it if you are a fan of the Warmachine universe, or if you like skirmish tactics games. Just be aware that there's a long road ahead for continuing development.
