I'm enjoying it, though it is thin in some areas (for instance, a scorecard; and sometimes units refuse to sentry-up which can be very annoying).
I played a Normal-game on Huge, Supercontinent, maxed-Mages and six "dimensions", though I did not enter a single one (not sure what the point is?).
- The AI does conduct diplomacy. They were constantly badgering me for tribute when I weak; and for non-aggressions/alliances when I was strong. Only the Skeleton king refused to play that game as he was on my border. We eventually went to war.
- Battle AI is shitloads better than Civ5. The AI seems to understand the nature of fronts and personal objectives; initially was trouncing me in my war. I lost a city fairly quick. That said, I'm not sure if I had "lucked out" with a spell, but I had Firestorm and that pretty much shit all over the skeleton hordes cramping my borders. The AI summoned tons of ghost wolves, while I on the other hand got the hand of fire elementals. The lack of a tech/spell tree leads for interesting random-gameplay, but I'm not sure I like it. Firestorm's ability to AOE-curbstomp the enemy completely changed the battles. I can't imagine playing the game and having that turned on the player -- watching your armies get fucked in one go is pretty brutal. When Civ came out there was a lot of talk about "field warfare", armies fighting out in the terrain. There is a lot of that in this game. Multiplayer should be very good.
- "Rebel" cities are the start are a great way to attain "foreign legions" of sorts. You get lots of unity variety in the game. My armies consisted of fire golems, goblin shamans, dwarves, the undead, and humans.
- Lots of interplay between units. Clerics healing, Mages throwing out spells, and forts/towers firing on units, for example. There is very good reasons to keep your units alive for as long as possible. The game works towards this goal by having severely beaten squads automatically retreat.
- Unlike Fallen Enchantress (which I am enjoying), the gameplay is fast and to the point. Constructing buildings is simple and you get instant feedback on the process. Unit-recruitment is couldn't be easier to manage. The game is mechanically sound. Your empire builds up the reserves to host its units and buildings; simple enough, and yet the player must seek balance.
- Insta-defeating a Great Mage by taking his capital is kind of stupid. That said, it takes a lot of manpower to bring down a capital.
- Still not sure what to make of the spell tree. On one hand it is okay, on the other you don't have any sense of direction. After a certain point I could only pick from 4-spells; and they were low-level rubbish. I could not figure out if I was close to the bigger guns or what.
Anyway, the game is pretty fun so far. I didn't experience any bugs or crashes like I did in the demo, so that's a plus.
