6 Erotic Steam Games Valve Sent Take Down Warnings To 6 IMAGES

A screenshot from banned Steam game Active Shooter.

These banned games were all created by developer BunchOD00dz. A developer in only the broadest sense of the term, BunchOD00dz cobbled together each game using pre-purchased assets and development toolkits. Asset Flipper takes its name from this process in a not-so-subtle joke about how easy it has historically been to get just about anything approved for sale on Steam.“From the esteemed asset flippers and shovelware pumpers that brought you gems such as ISIS [and] Suicide Simulator," read Asset Flipper's description before it was taken down, "comes another zero effort cash grab aimed at the fat wallets of edgelords and memesters. Do you enjoy wasting your time and money on the internet? Look no further!”That very topic made headlines just Tuesday when Valve announced a new policy that will "allow everything onto the Steam Store." Everything, that is, except for anything that is illegal or "trolling." BBunchOD00dz' own description of Asset Flipper would seem to be a transparent admission to its games being vehicles for trolling Valve and Steam users.In any case, Valve stated on Tuesday that the new free-for-all Steam policy would not go into effect until a later date when it rolls out new curation tools. Valve explained that the tools would let users "override our recommendation algorithms and hide games containing the topics you're not interested in."The new policy was developed in the wake of controversies surrounding erotic anime games and a school-shooting game . Last night, Valve elaborated on why he shooting game, titled Active Shooter, was banned from Steam."We rejected Active Shooter because it was a troll, designed to do nothing but generate outrage and cause conflict through its existence," Valve VP of Marketing Doug Lombardi told GamesBeat . "In addition, the developer had been involved in numerous misrepresentations, copyright violations and customer abuses. There are no second chances for Active Shooter, or its developers. And to be explicit, while the developer behind it was also a troll, we'd reject Active Shooter if it had been submitted by any other developer."You can read IGN PC Editor Tom Marks' thoughts on the Steam policy here , including why he thinks Valve isn't taking the moral high ground the way they think they are.
