TG is guilty as far as the original team selling all the rights to Europe. Ever since they have had no control over what happens, their hands are bound and mouths are gagged.. and not so much in a kinky way.
TG has made a lot of huge mistakes, they have fixed their ways, they are improving the game substainially. They have also been heavily cash flow limited for a long time, and have done what they could. They don't have the funds to just outright buy Unity and host it.
