Mount and Blade: Warband. I should love this game. Start as a mercenary, do quests, build an army, end up fighting in enemy lands, build support, and eventually start a kingdom of your own. Sounds perfect.
Except it's not. The quests are nigh impossible, and if you don't do quests, there's not much else to do. Most of them amount to finding a person that is running around the game map before a set number of days expires. Or I can build a small army of 60 men, but every enemy army is over 200 men strong. I have no chance if I fight them. Bandits are scarce to train on. So I just jousted a whole bunch and eventually got to build my army to 70 men. Then I quit, because 7 hours in and getting absolutely no where is not my idea of fun.
