Feral Interactive offers digital downloads on multiple online stores

So I'm thinking of ordering Borderlands: GOTY from Feral Interactive. Are they safe to order from and has anyone ordered from them before? Thanks.

Unfortunately there would be no way for Feral to make money off of their games if they were SteamPlay. Currently there is no way to distinguish a "mac" purchase from a PC one on Steam. Aspyr says:

"EH: We love Valve and are thrilled their games are finally on the Mac. Valve offers great technology with Steam Works and bringing that technology to the Mac is a benefit to gamers. There are certainly aspects of their technology that all digital publishers can admire.

On the sales side, Valve’s support of the Mac platform via Steam right now is reliant on publishers participating in Steam Play which is Valve’s program of releasing every game “Hybrid” despite who did the development work. Right now there is no compensation for the publisher if their game is downloaded but not purchased. For the publisher this is tough to swallow and I think this is a hindrance to Valve seeing the same market dominance on the Mac as it has on the PC. I believe if Steam even offered a Mac version of an existing PC game for just $5 there would be less of a barrier for Mac publishers to sell content on Steam, the consumers would still get a great gaming experience across two platforms, and a big catalog of great content could find it’s way to Steam."

That's good and all, but at this point it's Steam or nothing for me. Their great policies on cross-platform ownership, re-downloads, and insane sales make them the only digital game store worth paying attention to, for me at least.
