High resolution texture packs aren't a rare concept; Almost every mod-able game has them... They also usually have things such as low res texture and low poly count packs.
While a low poly pack is not reasonably possible, I'm under the impression that a low resolution texture pack would be just short of effortless. Wouldn't it be as easy as snatching the textures for the game, and lowering all of their resolutions in one big batch? Is that even possible (i.e. lowering all the textures in a batch at once)? Are there any roadblocks I'm not thinking of?
Even if not undertaken by someone here, I'd like to know whether or not it's technically possible?
