The Ocarina of Time carry-over LP from their days with FATLPs. Abandoned before Water Temple due to endless technical difficulties and a loss of enjoyment.
Their time with FATLPs is equally Old Shame-ey, but at least they actually completed the games back then.
The very short-lived Sonic Adventure 2 LP. Abandoned 5 parts in after it very quickly stopped being fun, which undermined the fact that it was mainly to mock the game.
The Majoras Mask LP that Thorn tried doing mid-way through OoT. Ultimately abandoned after the Woodfall Temple during the Bomberman Hero LP.
The original attempt at the Pikmin 2 LP (which only reached 5 parts) is outshined by the new one in every possible way.
