Might not be competing on genre/platform, but it's competing for the wallet. As I mentioned earlier with supermarkets keeping quite strict to £44~46 for a new release now, not many people can afford £90 on top of their shopping to get both games for the kids. Years ago you used to be able to get COD/FIFA for like £25 if you spent £50 or more on shopping.
Mario/AC is going to beat out Wolfenstein all year round for the battle of the wallet.
Not to mention this is the UK, not many people here see buying Wolfenstein as some political statement. It's a critically acclaimed game, yes, but it's just another great game behind Mario and AC which are far bigger IPs and household names.
That poster has a point releasing this at the same time as Mario, let alone AC, is just stupid.
Sorry I don't buy that argument. Would these be the same parents who in a span of 7 days ended up buying their kids HZD, BOTW and Wildlands? Did they have more disposable income in March?
