Most people with negative reviews about this game have complained about it not being what it is not - it is NOT a casual strategy game with quick battles and few decisions, but it is a slow-paced, advanced, hardcore strategy game.
Now, today there are many casual players not willing to put so much time in single games, so it is understandable that this game is not well-regarded by some people.
The combat is really exciting when you finally find the enemy, and have to think about every single step your soldiers take, as the consequences for mindlessly charging into battle can be very grave. There are many weapons, different ammuniton types and some other equipment such as first-aid kits. Before commencing an attack, the player must choose soldiers for their squad, pick their equipment and think about what statistics they have, and as thus, people who put time into thinking about that can have a huge advantage in the battle. In combat when the soldiers are deployed, each soldier has a certain amount of action points, which are drained by moving, shooting, changing weapons and such. There is a map and a compass for navigating, and hills and trees for hiding. The player is told only where they are spawned, and where the enemy is spawned - common sense and a good strategy is required in order to find the enemy. However, there is A LOT of micromanaging, which I like, but I do know that for some people looking for a simple game, that is unfitting.
The graphical theme is lovely with its sharp colours, and soldiers look great. There is an official "realism mod" by the game developer, which changes all textures to look realistic, which makes for a nice change to the aestethics should one get tired of the bright landscapes. Also, the game has a steampunk theme, uniforms look like they are from the 19th century, there are airships (as the title says), pith helmets, monocles, you name it!
If I were to choose something to be added to this game, then it would be vehicles in battles, imagine steampunk tanks and airships cruising around and attacking the enemies, for more significant battles. Also, multiplayer would be extremely fun!
I love this game, but I know that it is not for everyone.
