I asked about this just yesterday actually, in response to a question on our forums. Here's what I was told:
Our first priority is getting the 2.0 version of the existing game out for web and then mobile. After those are live it will be a high priority to get Adventures live. "High", but not necessarily "highest". Adventures will be a major effort requiring substantial enhancements to the engine, AI and user interface, and we already have a long list of post-launch enhancements to the existing game.
The Adventures news is disappointing, but understandable. It looks like the most complex Dominion expansion ever made, by a lot, and I understand if that takes some time.
This post did bring up a point I wanted to make while you guys are working on this and before it's too late. When you release Dominion 2.0, will you be taking down Dominion 1.0? I really hope you do not, and please hear me out here.
As you've said, you'll be releasing 2.0 out for the web and mobile first, then you'll work on post-launch enhancements (including, presumably, any suggestions you guys implement from this thread), and then Adventures after that. Since Adventures will not be coming out with 2.0, and a variety of enhancements will not be happening until after launch, I fear that when Dominion 2.0 launches, it will end up being a net downgrade for players of Dominion 1.x with Salvager installed.
Without Salvager, Dominion 1.x is almost unplayable, and before Salvager came out, many players were driven away by the official implementation of Dominion Online. From what I've seen, in preview screenshots online (and please correct me if I'm wrong), Dominion 2.0 will be reusing the same interface as Dominion 1.0, down to the positions of cards, the positions of buttons, the off-screen log and chat windows which cover the game when triggered, etc. So while the stability improvements and whatever features you all manage to throw in by then will be great, the dropping of Salvager support without the features re-implemented in the new version of Dominion will mean that for the hardcore players, Dominion 2.0 will be a
downgrade and a return to features of Dominion 1.x that made people quit in the past.
I guess the point I'm trying to get to is, if you can keep Dominion 1.x up until Dominon 2.0 is competitive with Salvager, it would save us a lot of headache. If you're planning on having all the Salvager features implemented at launch, then good for you guys, we'll figure it out I guess.
