So I thought I would put my $.02 forward on what I'd like. First, if the rules are even as complex as the have been in the playtest, I want to see an electronic character builder. Since I suspect they will be more complex, I really would like the option, since it makes it lightning fast to make a character.
I am an Android user, and so I am used to app purchases as well as "DLC" to get additional options. On my PC, I use Steam, which also has app purchases and additional DLC.
What I would like to see is WotC partner with an existing platform to deliver their builder rather than reinvent the wheel with a product they design themselves.
I am perfectly content with Steam, and I know that Steam has offerings in Windows, Mac and Linux environments, so things are pretty much covered there. I know some folks really don't like Steam for different reasons, and I'm not entirely sold on them, but I know that for me, it just works.
would love it if I could buy an App for my Android tablet, and there was also an option for iOS as well.
So here's my suggestion: everything in the game at "app store purchases." I would release the character builder for the core rules for free, and then price ad-ons at around $5 per book or $2 for something like a month of Dragon magazine.
At that rate, if I were playing 5E I would pick everything up.
Now the thing is: I know this system could be pirated, and would be, but I would buy it like crazy. There are sources for Android apps that are illegal, but the thing is, with 95% of the apps at $5 or less, I don't know anyone who bothers. Steam is having a sale at the moment, and I've picked up so many games that I might not even get to play all of them. That's what keeping the price low means.
Now the examples I've given (Steam, App Store for Android, Apple Store) are something I'm sold on, just an example of things that work right now that WotC could partner with. What I would not like to see is a proprietary app that locks out a ton of people and, frankly, doesn't work very well.
If I'm playing Next, that's what I would hope for. I hope someone at WotC is listening...
