Sony should license decima. I think its important to have extremely capable engines that can be licensed by devs. But it seems unreal is dominating, competition is always good. And I think decima can be a good competitor.could also be a distraction. if you want to sell if you have to support it. support costs are pretty much the same if you have 1 customer as if you have 100 customers.
i dunno. not saying they shouldn't. just saying it's probably not a easy yes either.
