I dont think price is the right tactic.
At this point it has to be clear the reason for the differnce in sales is its not as desirable as the playstation 4.
They need to change how their brand is percieved, and the games for the system.
Ei. keep showing titles that arnt shooters, show it has more diversity in games than people think. That people that see it as a dudebro box are wrong.
Id get more european game studios, and ask them not to make american styled games, or shooters.
Maybe try to get more japanese games for it too.
