For me, MU Monarch Sea is one of the best games I’ve played. The storyline really pulls you in with its ocean-kingdom theme, and the gameplay is smooth and exciting — every battle feels rewarding. The graphics are impressive, with detailed characters and breathtaking sea-inspired environments that make the world feel alive. The soundtrack also adds a lot to the experience, giving every adventure an epic vibe. What I like most is the community, since teaming up with other players.

Your game was very laggy at the beginning, there were many players, not so much lag, now there are only a few players, especially in war and events, it's not enjoyable to play anymore, waste of effort and money, you can't even do anything, all you want is to make money, don't make excuses that we can move to someone else, you're just proving that you only think about yourself and want to make money.

From 5 star to a star. Hard to play now if we have to compete with players using bots and multiple accounts for farming. I personally enjoy this game but people pk without any consequence is making it hard to farm for loot. And it is already hard enough to farm.
