Speaking to PCGamesN , Tripwire Vice President Alan Wilson said the exclusion of modding tools from accessible genres -- most notably shooters -- is a choice they "really can't wrap our heads around."
"Why would you stop people from modding your game?" he asked. "Why would you prevent people from being creative with your material? Just look what [DayZ has] done for everyone concerned, for example. Arma 2 has been on the top-ten sales charts on Steam for about the last four months solid because of what one of their employees did for fun in his spare time."
Originally a team of spirited modders, Tripwire elevated to a full-fledged development studio after Red Orchestra took the grand prize in Epic's first Make Something Unreal contest. The standalone followup, Red Orchestra 2, gets its first expansion later this year.
"Frankly, we can see zero downsides to allowing people tools and letting them mod a game," Wilson added. "I never understand why companies effectively block people from doing that stuff."
Meanwhile, DICE recently reiterated that the closed environment it has established in Battlefield 3 should remain that way, warning players not to use a mod which affects the game's color saturation.
