FYI, Mangagamer already announced they were going to release Umineko on steam, HOWEVER the release won't have voice acting (I think), and will use the Umineko Pachinko Game sprites (this version uses the PS3 spites):Kyuunex wrote: Why not start a kickstarter/indiegogo and legally license this game and then publish it on steam? I would definitely buy if that happened. (I'm a heavy steam user).

So if you want you can buy the game on Steam, but I think this version should end up much better than the Steam version. Reasons not to make a Steam patch to add in what's in the Umiproject version is addressed in the FAQ of Umiproject
