As a Brit, I wouldn't put much stock into FE's lack of performance in the UK. Nintendo barely have a presence, and the delay in release has obviously not helped things.
Good to see it doing better in other European countries at least. Will get it myself in the next couple of weeks.
Wasn't expecting Overwatch to sell massively. Those are good numbers for a new IP. If it's as good as what people say then word of mouth will help it along but it never seemed a breakout hit to me at least on consoles.
