As I don't work for BB. I don't know what they consider to be their "user retention issues" from market research.
However, you can find many real life examples of professional sports teams trying to improve ticket sales and merchandising by doing jersey changes.
Or, guess real life strategies don't work for a fictional sport to accomplish the same real life task?
As to
what keeps us will attract new users
: blanket statement that is over-generalizing, and not entirely true.
Many new users, don't have issues right off the bat, with things that become problems for users that stay on and play continuously.
Did every single person figure out within 2 league games, that the outside shooting is busted and LI is heavily favored?
Does everyone figure out within the first 7 days how ridiculously hard it is to find an AFFORDABLE trainer?
Do new users even know what an "affordable" trainer is?
etc
etc
etc
While I agree whole-heartedly that the developers need to not Shun the current user base and longtime users in an effort to only pander to trying to retain new users. Retaining new users is also something that they can't ignore.
The developers need to find a way to do BOTH at the same time. And not just flip flop between which group they try and cater to. Surely they're not suggesting that B is without any problem at all that longtime users and new users both get frustrated with?
