So the Peak Games one is more unfortunate as they don't even exist in the same realms, they are about mobile phone games.
War Banner/Warhammer I get, although it's taken them a while to slam down the C&D. Now, I might be reading too much into this but Andy Hobday recently took on War Banner didn't he? And he went there and essentially took the game he had created, Test of Honour, which meant Warlord Games could no longer stock it.
Thing is with them, they have a number of ex GW employees. It just seems to coincidental that War Banner suddenly gets a C&D after over a year of operating otherwise.
