Darklands
It has the best aspects of games like Baldurs Gate, Oblivion/Morrowind, and pretty much any RPG i've seen. Probably the best open ended game of all time as it allows you to do anything you want, similar to Oblivion, except with far more involved and interesting results. This is a game that you can do nothing but wander the countryside and still have fun.
Its setting is medieval germany.
The most interesting aspect of the game is that everywhere you go you have MANY choices of what to do, in terms of conversations and scripted events.
Funny Darklands moments:
Purposely have a low skill character make explosives in an inn in a large city like Aachen or Frankfort. Usually resulting in many people dying and various forms of hilarity.
Refusing to enter a city through normal means IE:
When arriving on ship pray to a saint, form of spell casting in the game, so that you can walk on water before reaching the dock.
Use Alchemy to cause a "distraction" at the gates or wall.
Sneaking in during night having Nightwatch catch you resulting in a fun battle and making the guard of the city go .
Other funny things:
Ask for sanctuary at a Church having done no crime, causes suspicions and the whole city wondering WTF? You then surrender to the guards but try to violently escape, but purposely get caught. Depending on what you do this either sends you to prison or to get killed, if in prison pray to a saint or use alchemy to do something hilarious. If you are going to be killed however wait until the last moment when you are on the gallows or ready to be beheaded and escape, having someone with the escape ability, alchemy, or saint, kill everyone on the gallow area and leave.
Since you can gain fame/infamy in this game and its VERY well scripted in terms of events there is literally infinite possibilities of fun/hilarity in this game. the overland map is fun as well, like you can run into Knights and joust them or whatever or run into merchants that are under attack, rescue them, then change your mind and attack them yourself.
You can even attack a castle and challenge the lord to combat, with a reason or at random, and kill him which is always fun.
The combat system in this game is similar to a Baldurs Gate type game.
