It's like heroes of might and magic, only at maximum speed. Well, no events on land. Moreover, there are events on the water, like “You have found a lost island, fight the guards and take the treasure.”
Like heroes, there are two modes - global map and battle. The global map, as already mentioned, without events, BUT is all covered with cities, there is no ownerless land (plus quests and individual mechanics, not just for each faction, but for each lord!). Diplomacy is conducted there, on the global map. Alliances, wars, trade. The battle mode takes place in real time, with the ability to slow down/speed up and pause.
In short, the game is ok, but the price... Three years ago it cost me 70% of my monthly salary. Now you can’t officially buy it and I can’t even count how much it costs now.
