From what I've read so far in this thread, I think Maximus meant to title it "Most Annoying Game Controls", because "uncontrollable" suggests a game that can't be played properly because of how its controls actually work. System Shock and Decent have fairly elaborate controls, but once you get the hang of them they offer an unprecedented amount of movement freedom.
Here's a modern example of a game with some of the worst-coded controls ever: Jet Gunner. It's available on Steam and I haven't really been able to play it yet due to not just one but TWO major issues related to the controls. The first is that unless I have both my 360 controller on and my Logitech gamepad plugged in (or any DirectInput device really) I only get a framerate of 5. With both going, my framerate is a solid 60. That's strange enough in and of itself (though speaking as a programmer I can hazard a couple guesses as to why it's doing that), but the more insidious issue is that I can only control the menu cursor with the keyboard, I can only make menu selections or bring up the pause screen from my 360 controller, and I can only actually control the game from my Logitech gamepad.
...yes, I'm dead serious. The controls in the game are nothing more complicated than move, shoot and jump, but the I/O is coded in so incredibly badly that it can't just let me use one device, it has the controls split across all registered devices depending on context and changing my control options from the options menu doesn't seem to do much of anything. x_x;
Now true, it's an indie title, but that doesn't excuse a control system with this level of issues when it's being sold for money because as it stands, I can't really play it properly. :P
Another good example would be the DOS version of Mega Man, which I actually went into detail about in my coverage of it on ADG way back in my second episode ever: http://www.pixelships.com/adg/ep0002.html
Basically, Mega Man for DOS shouldn't have anything more than Move, Jump, Shoot, and Menu, all in easy to reach spots, and the Shoot key should double as a key to confirm selections. However, the game instead has the following controls:
Arrow Keys - Move
Spacebar - Shoot (does NOT confirm selections)
Enter - Confirm Selections
J - Jump
Escape - Open Weapon Menu (does NOT close it)
P - Select Plasma Cannon in Weapons Menu and Closes It
V - Selects Voltman's Weapon in Weapons Menu and Closes It
D - Selects Dynaman's Weapon in Weapons Menu and Closes It
S - Selects Sonicman's Weapon in Weapons Menu and Closes It
E - Uses an energy tank in Weapons Menu
Technically another good example is the default controls for FX Fighter. Try pulling off a quarter circle forwards + punch move when A is up, Z is down, X is left, C is right, Q is kick and V is punch. Thankfully though, FX Fighter lets you change the controls, but still, the defaults are just downright embarrassing. :P
