I made Sim Vassal as my first decent game about 4 years ago; a lot of people still like it so I decided to put it up here too.

Info:

SimVassal is a medieval RTS based in the times of the Inquisition. You are a vassal, an owner of land given to you by a higher noble. Because of scientists' questionable work being sponsored by your lord, the inquisition has reason to find you deserving of death. Fend off their and other's attacks and you may survive to live the happy life of a vassal.

Don't be thrown into thinking you have no control by the different resource system. Instead of gathering metals or wood, you can employ 'serfs' to work on your land. At the end of the year each serf pays 50 gold in taxes and your fields are harvested giving you a certain amount of gold.
Pay attention to the instructions given to you in the first year as they will help you progress faster and stay alive longer. Upon winning you will recieve a code, pm it to me if you want your win proven to others, use it in the game and you'll have another prize.

Please note that this game temporarily changes your resolution to 640x480.
Though the music contributes heavily to mood (you'll see at the end) you may turn it off with <m>, to turn it back on press <k>.
