Yep, I only got an iPhone as I had quite library of content already purchased on my iPod touch and ipad, that I wanted to carry over. BC helps to get you tied into that system. If its not there, there's no reason to continue to purchase products from that company as it is like you're investing in a totally new platform.
I already feel comfortable ignoring the Xbox One in favor of a PS4, for example.
Plus, how many people are really taking into account this past generation has been 8 years long? When thinking of "old games" are a lot of folks talking about their childhood and games barely remembered?
I honestly wonder what happens when push comes to shove and contemporary buyers must make a purchasing decision between an XBO, a PS4, or just going PC. Will brand loyalty be that strong when there's no continuity of content or investment?
Of course, in the eyes of modern game publishers like EA, it's all about yearly franchise updates and pushing ever-more for games as a service. In the view of many in the industry, it seems the ideal set-top living room box would just plain be something where nobody buys or owns games, and you just pay a rental fee that's ongoing. The box gets swapped out regularly as an upgrade, and that's how you lock your audience in.
If they've cultivated a gaming audience that is really just happy with that, more power to them I guess.
