I.T. Kid

Virtual Champions League is a football game that follows a club through the rounds of Europe's biggest competition, opening at the quarter-finals. The arrow keys move and run, Z passes and X shoots, and you only ever control one player: the one with the green circle round him, which the game hands over as the ball moves. A fatigue bar under the player turns red when he has run himself out, and a tired player cannot strike the ball properly.

The opposition gets harder with every phase, and winning the championship is worth a 275-point bonus. It is a GameSheep game by WitchHut, and the closest thing here to a full campaign in a browser tab.
