I'm not particularly fond of football but I must admit I had some fun while testing Football Challenge, a simple 3D online football simulator that you can play for free.
Be aware that this is no FIFA or PES. In fact football sim junkies may feel a bit disappointed at the game's simplicity in graphics and controls. Here you won't get the official player names or uniforms – in fact you can customize the team's shirt any way you want. What's more, there are no special moves or button combinations: the arrow keys and two action buttons (kick and pass) is all you need to play. On the other hand, this easy gameplay is what makes the game attractive even for people like me who don't know what an offside is.
Football Challenge includes both offline and online gaming modes. You can play against the computer and also enroll in online tournaments just by filling in a simple form and creating your team right away. The game will automatically find a match partner for you to start playing. Obviously, the more games you win, the higher you'll reach in the player ranking.
Football Challenge is a simple football simulator with support for online games, great for some easy fun but definitely not aimed at hardcore football fans.
