Appeals to niche gamers and those with a lot of patience. Attractive ambiance. Strategically, it has no staying power.
This game will appeal to those looking for "something different".
I think that this game will appeal to older gamers (25+) because the game can last 1.5-3 hours ( with the longest game that I ever played being 6 hours long ). To put it into perspective, it takes about 20-30 minutes for ICBMs ( Inter Continental Ballistic Missiles) to hit their targets due to the long distances / lengthy flight times.
Submarines, the slowest moving vehicles in the game move at a rate of 1 pixel per minute so the game requires a lot of patience, initial pre-planning and readjustment of playing style, relative to today's RTS ( real time strategy ) games . I think that this slow-fast, stop-start combination of fighter planes and bombers versus submarines makes the game more realistic and always tactically frantic in a "who will outrange and launch ordinance first?" kind of way.
You can speed up time but because of the stop-start, time-critical nature of the game, and the importance of defending against attacks, I found myself playing the game in real-time ( rather than using the "fast-forward time" button ).
The ambiance of the game is very attractive: minimalistic graphics and sound; so as an art project, this game is very successful.
Strategically the game is not very deep because of the static nature of the world map. After figuring out the nuances of the tactical combat. You will figure out an overall winning strategy within a few games and after that, unless you play multiplayer (and even after), you will most likely uninstall the game.
I bought the game based on the fact that I couldn't stop laughing after reading the outside of the box ( British humour / Physics humour ).
Pluses:
The cheap price point.
The low resource requirements ( there is a linux version on the developer website ).
The art style.
The humour in the manual and on the box.
Minuses:
You cannot make the game more challenging.
Once you figure out the rock-paper-scissors nature of the game, you won't feel the need to play it again.
