I don't think GoT or TWD will age well and that both will feel dated in a few years. Play wise TWD>GoT and by a large margin. If your choice is between these two TWD is a no brainer, but I wouldn't buy either unless the theme is one you really like. However I don't think either game does its' theme justice.

Star Wars is a very overpriced miss. The theme will hold up but I think the game play will get old fast. I'll play it on location, but it's just not worth a spot in a line up unless you don't have an SR game (and questionable even then).

I expect Batman 66 will be the sleeper of the bunch, but would hold off buying until at least after the next code drop. Current game play is very under-rated and all signs are that Lyman will make it terrific. The art package on the LE is the best (IMO) and the topper is the best Stern has done so far, but there is no difference in game play so Premium is the best value. If you want Batman now, some distributors may be willing to cut you a deal to move existing inventory now (bet those deals go away when the code is finished). From a best integration of theme standpoint, Batman is by far the best of your choices.
