I want to hear about he biggest Game Glitches Ever. I mean to the extent of ones like:

-The Oblivion Glitch_where you use the paintbrushes to beat the game in like ten minutes, or...

-The Legend of Zelda:TP Glitch_where you can get the Master sword through some unique jumping and skillful    fighting, making the game 5 times easier in the beginning and letting you skip a chunk of the game.

 Discuss!

My friend found a glitch in Twilight Princess where if you save in the cannon room (I think thats what he called it), you're unable to leave the room after. So your game file is ruined because your saved into a room you can't escape. he lost hours off his game because of it.

The melee black hole glitch is pretty big and fun to do.

Yeah I heard of that, I would be so pissed off! But doesn't that only apply to one version of the game (Cube or Wii?)

Also the pokemon red/blue missingo glitch.

As for my contribution to this thread, the FFVI vanish+x-zone glitch.

...and I think that TP cannon save glitch only applies to the cube, because I remember saving there (the room you end up in after getting shot out of the cannon, right?) and nothing unusual happened. 

can someone explain this oblivion glitch to me....for ummm....just so i know, not to use it or anything ;)

Pretty neat trick, but it screws up alot of the game.(You can ride your horse as a wolf!!)

The original generation of Pokemon games had so many glitches. Just 3 from off the top of my head:
1. Missing No.
2. Getting Mew
3. Glitch City

In the game, when you drop a paint brush it floats, so if you drop one, then get on it, and place another one you can eventually make a large stair case, and when you get high enough you can drop into this tall tower. When you drop in, and exit the building, the ending scene of the game commences.
(Don't own the game, but I know this works. Could screw up your game I guess)
