Very addictive game, but requires a huge amount of time and patience to play. It gets repetitive after some time.
When you first have experienced the thrill of attacking someone else and taking their villages, you get hooked. The excitement of brutally beating another player and crushing your enemies is a huge morale booster. You get bigger while your enemies gets smaller.
But when you've been on the other side of the battle and experienced the thousands of incomings day after day after day, you'll realize that you've spent every spare minute you had, and even sometimes time you didn't had, to defend yourself and tagging new incomings. Even when you're trying to sleep, the incomings keeps rolling in and will probably keep you up at night.
That's when the game start to feel tiresome and repetitive. I should know, I've experienced both sides.
The game requires a huge amount of patience and time. It can take years for a tribe to conquer a world (= server) from start to end. The game is not to be recommended for anyone with a family or girlfriend.
