Stuck!!

The Game: Star Wars: Dark Forces (PSone, PC)
The Level: Mission VI - Crix Madine’s Fate
The Brick Wall: Liberating a political prisoner from the clutches of the Empire sounds like a worthy pastime. What they fail to tell you is that the Imperial Detention Facility is a ludicrously convoluted maze of lifts, key cards and switches that broke many a brain with its brazen manipulations of conventional elevator shaft design.
Stuck-o-meter: High; it took forever to solve without cheating, but once you had it figured out it was a work of art (by mid-90s standards, at least.)

The Game: LEGO Star Wars (PS2, Xbox, GC, PC)
The Level: Ruin of the Jedi
The Brick Wall: You must Force-pull a platform out of the wall and jump up onto it. Then, before it retracts back into the wall, you must quickly Force-pull another, higher platform and jump onto it in order to reach a switch. Repeat three times. A simple concept, but made miserably difficult by poor camera angles and screwy controls.
Stuck-o-meter: Medium-low; the game is almost over at this point, so getting stuck on such a petty obstacle really sucks.
