Out of them tho, Tactical Adventures seem to be the only ones that care about DnD, and they have the engine/infrastucture avaliable to make more DnD games. All they'd "need" is some writers, the official* stamp from WOTC and then either make fully original DnD games or, like what Owlcat did, use Adventure modules as a base
I have to agree, I really like Tactical Adventures and hope they keep going.
