I am 46. I play BB for more than 10 years and still love and hate it. Besides some minor tactics and economy adjustments, the game is still very addictive to me.
Although, I believe it is too complicated to have some motivation for the beginners. The game is not easy at first sight, they won't win matches very often, the budget, arena and player skills will increase very slowly, and this is not compatible with most new game players. The world is a much faster place now

BB needs a faster, simpler, more dynamic and attractive version for beginners and younger players. These new generations have a lot of distractions, they won't bother with games where they can't evolve at a fast pace. The App won't help, but a better mobile responsive website is essential.
I can't think in a better solution than to have 2 versions of BB, because you will never please both sides of users. One for the slow pace old school fans. Another much simpler and faster for the newcomers. Sort of BBRookie, where you can experiment a simpler version of BBVet, and join us when you are ready to try a new challenge.
Two different approaches, two different markets, two different marketing strategies.
