BFG only has about 200 games on Steam (click here for list
), but they include many notable titles such as Mystery Case Files and games by Eipix and Elephant. Most of these are collector's Editions too. The latest MCF game "The Revenant's Hunt Collector's Edition" still costs $13.99, but many are only $2.50 to $4.50 during the current Steam Winter sales. For those, like me, who don't want to pay monthly fee to BFG, this is a good way to get some of these titles.
I encourage BFG to keep selling its games at Steam, which is a bigger, better version of the BFG site. Steam has over 70% of the digital game market, so it is not going out of business any time soon. Should BFG go out of business, I would be nervous about losing all the games I've bought there.
