Black Knight

The sound is super-professional, and the graphics look like a Disney cartoon - and the gameplay? Involves walking along bashing everything you see with your club.

To be fair, there are two kinds of attack - one where you just hit the peasants to extract their taxes from them, and one where you 'go medieval' by holding down the mouse button first. For addded excitement, you have to avoid hitting Matilda the witch, and there's a Gold Miner-style shopping spree at the end of each level (once they're collected, the King doesn't seem too bothered what you spend his taxes on).
