Unlike most lines for Construx, GoT is a dead show now and overall outlook on the series has been very poor due to its final seasons. The timing on this is horrible and it wouldn't have been a problem if this was a line created years ago.
Mega needs to drop this line soon and pick up a new license over something new and upcoming if they want to pull in more sales. For example, the new Witcher series is releasing later this year and while the only controversy is based off of the cast and characters appearances, it's better than what happened to GoT.
However, if GoT is what Mega REALLY wants to do, then just make them in the Heroes line instead.
