the game sounds cool but when I go to the site it tells me nothing about how to get it for the PC, plenty of "get it on PSN / XBLA" but for PC it just says "downloadable" without giving any kind of links for how to download it.

I also see GFWL at the bottom of the page, but when I did a search for it on the sites forums I saw a bunch of "get it on steam" remarks .... so is it a GFWL title that is sold exclusively on Steam or some back-asswards thing like that?

how fucking hard is it for WB to put up some details for how to actually GET the damned thing, do they not want people to play it on the PC or what?

Yep.

I guess I should have tried a bit more, it is sold on GFWL (I also found it on GamersGate) and Steam is not required.

I kinda got aggravated by not getting answers on the game's site, and when no information is supplied it typically means that "they" are expecting everyone to innately use Steam for everything relating to PC gaming so it's no necessary to supply information on how & were to get it.
