Pretty much any of the upgraded, true to Morrowind style armors and weapons that have been made for Oblivion would be awesome to see converted back down to Morrowind. Especially now that I think most of the texture techniques will cross right over thanks to the MCP.
even oblivion mods not from morrowind would be good on morrowind, i cant run oblivion on my PC, keeps CTD before the main menu, so im stuck with morrowind, and the farther technology goes, the better the mods, if people still remember morrowind.
BTW, need any help with the tyrael armor, or is it pretty much finished?
