Torrent (http://adf.ly/3914570/sukebei.nyaa.se/?page=download&tid=23897) (10.03GB)
I've downloaded the compilation and split it up into bite sized chunks and uploaded them to Mediafire. Unfortunately there's a pretty big overlap due to most of the games being on collection DVDs, hence the big torrent size. Basically Izumo 2 has Izumo 1, 2 and the afterstory expansion Izumo 2 ~Gakuen Kyousoukyoku~ on the same disk. Izumo 3 however also comes bundled with Izumo 1 and 2, but not the Izumo 2 expansion. Izumo 0 is on its own disk though.

Izumo 1 / Izumo 2 / Izumo 3 (http://adf.ly/3914570/www.mediafire.com/?yb98od7v5f380)
Do make sure to get the "Izumo 3 extras" file in the last pack if you want to be able to install Izumo 3. Also Izumo 1 and 2 can only be started by running the autostart.exe files in their respective game folders; using the Izumo.exe files will not work. Izumo 2 ~Gakuen Kyousoukyoku~ does not require this (it doesn't even have an autostart.exe).
