Yep they’re owned by Tencent, however from what I’ve read, seen and experienced in game, Tencent don’t have much, if any, of an input on the development. Yes I know that Tencent staff sit on the board of GGG.
GGG did a rough patch a few years ago, I was out of the loop and not playing then, but it seems it’s made a fine comeback.
Lastly, if I’m not giving my money to a NZ company owned by Tencent (who I agree are very not cool), I’m most likely giving it to some equally bullshit, corrupt, money grabbing AAA developer in America so what’s the difference?
