I usually look at these games as a source of cheap(ish) miniatures. I have played a few games of zombicide and Death May Die, but the minis are the draw.
Unfortunately, the figures are on the upper end of figure size. They sort-of work with Stargrave sized figures, but look better against the new Infinity models.
The figures in this game look to be on the large side as well. I may eventually pick it up at retail, but even if their shipping values stay as they are, there would be little change out of $200 to the UK.
I did back Zombicide Invader, and I don't remember it being this complicated. I'd need to check, but I don't remember recoiling in horror at VAT or delivery charges. I know the rules have changed in the last few years, so maybe I was lucky.
