Regarding sales; If they brag about it, good sales, if they don't, bad sales.
Well they seem to really pile on the talk of Revelations, so i assume that at least did well.
Or at least brag about how many they shipped to stores, if not actually say how many were actually sold.
Well, units shipped tends to correlate with units sold. a store won't ask for more shipments if they still have too much unused stock. So if they brag about shipment numbers, then it means that there was a demand for the game.
I do wonder the exact numbers in comparison with LoS1 though.
Both in initial preorders by stores, and in sales. I imagine that more stores ordered LoS2 than LoS1, but LoS1 sold better than LoS2 anyway
