I'm happy it is coming out, like the hexes, looking forward to the economy changes, tile conquest. Don't particularly mind spreading warfare out over the terrain.
Still, I voted no, and here's why: because of two things that look likely: no combined arms and rocket arrows. One unit or one unit type per tile, either way it's just dumb and necessitates rocket arrows. Rocket arrows are arrows with the range of modern artillery rockets. Bombardment is fine, but archers, catapults, and premodern cannon all had ranges less than a kilometer, basically all in the same ballpark. If they can shoot into the next tile, that's fine--the battle is on the line between hexes. But if they are shooting two tiles away I can't handle it. But they have to because you can't have archers undefended (that would be unrealistic) or missile weapons with no more range than swords (unrealistic again) and with only one unit type per tile you can't defend archers with spearmen. And we have to have one unit per tile because two units per tile doesn't do the same thing. (No its not realism, we only care about playability) Well, it might make it unplayable.
I'm not asking for painstaking realism, and can suspend disbelief, but there comes a point where the same gameplay benefits can be attained without the cost in credulity stretching but instead the disregard is flaunted. Yes a single truly bad feature can ruin the whole game.
Perhaps it will work out, and I will be pleasantly surprised.
