Thanks for the reminder - 1.008 is now out for Valley 2.
There is indeed a very limited amount of time for older titles, as is pretty natural with games. The Valley series, Tidalis, and Shattered Haven are not considered to be in active development and likely will not be in the future. That said, it's kind of like any new game that comes out from a AAA publisher -- they pretty much are not in active development ever again once you have them in your hands. All of our games went through a post-release period of higher activity, but we can't really sustain that over the long term since it does not generate money in any sense, and typically if we are not generating money we are going out of business.
AI War and Skyward Collapse are still off and on in active development, and otherwise are in maintenance development. Our other titles are in what you might consider "extended maintenance."
I know that's probably not the news you were hoping for, but I figure I might as well be straight with you about it rather than beating around the bush. We have only two programmers, two artists, one QA person, on PR person, and one composer. The only thing that keeps us employed is making new games, or continuing to keep the ball rolling for games with a lot of momentum at the time. Valley 1 had some enormous momentum for a long while, but as with all games that fades eventually and it becomes part of the back catalog.
Any further questions, do let me know. Thanks!
