 Peter Bright of Ars Technica directed criticism at the ability for third @-@ party websites to allow gambling and betting on match results and in @-@ game items , similar to controversies that also exist with Valve 's Counter @-@ Strike : Global Offensive . Using Dota 2 as an example , Bright also stated that he thought Valve built gambling elements directly into their games , and had issues with the unregulated practice , which was often used by <unk> players and regions where gambling is illegal . In response to the controversy , Valve and Dota 2 producer , Erik Johnson , stated that they would be taking action against the third @-@ party sites , saying the practice was " not allowed by our <unk> nor our user agreements " .
