I started playing La Brute a couple weeks/months ago, and I got pretty hooked to it..
It's a very simple game where you sign up by following this link: labrute.
Once you get there, you enter your desired nick, and you already have an own brute.
The goal of the game is to gather experience. You can do that either via the daily fights (3 of them: 1 point for losing, 2 points for winning), or via disciples(eleves). For each disciple you get a point when they sign up, or when they pass a level.
It's taken me a bit but my brute is now up to level 15, which isn't that bad but not great either.
The interface is in French, so it takes a bit to get used to, but it's a nice exercise.
