Civ Wars - a great game that has stood the test of time. The community, while not as large as it once was, is still playing. The game spent many periods of time stagnating - The meta didn't shift, players came and went... But, the game lives on.
This map is a line war game. It is tug of war, rock + paper + scissors, and economy/technology/military balance game. The fun is in how each game can play out. Individual players can make a HUGE impact on the game, but in the end, teamwork is king. Top and bottom lanes typically are "support" players, but not in the typical definition of the term. These lanes are the military force in this map; they invest everything into building a force and upgrading them to beat back their respective opponents. Mid lane is sort of the team captain and gives support to the side lanes. But, despite giving support to the side lanes, the mid lane is more of the "carry" role in this game. While the side lanes typically duke it out every game, the mid lane chooses where to spend their gold and also races through technology more quickly. It is the mid lane player's choices that usually decide a game.
The three lanes share similarities in game play, but also end up feeling different. You could play a dozen games as top lane and it would be a very different experience playing bottom lane. The armor and damage types of units is different and therefore your army composition will differ. Once you have experience on top and bottom lanes, you can try out middle for another new experience. Middle has the same units to choose from as bottom.... But also must juggle more things by assisting other lanes as well as fighting for middle and teching up and increasing income and....
The map has been around for a while. The formula hasn't really changed. The developer responsibilities has been passed down from the original developers. The current dev is innovating and adding new content to mix up the meta and is bringing about a lot of hype and change that is a breathe of fresh air for the game.
If you have never played before, I recommend giving it a shot. It can be a bit overwhelming your first few games, but if you ask for assistance there are a lot of players out there in the community that will tell you basic unit compositions and tech orders.
