This announcement is for the benefit of anyone who already owns the game.
As planned, ZGA is now unavailable to anyone who doesn't already own it. I'm still not sure how long this will be yet, probably between a few weeks and a couple of months, depending on what state I decide to re-release it in. If you want to know why, I explained in my last announcement on the subject: http://steamcommunity.com/games/467820/announcements/detail/575721288024011684
Anyway, as for what you can expect while the game's withdrawn from sale:
-Probably it's now highly unlikely that you'll be able to just go online and find a game. In light of this, I've made a new sub-forum for arranging matches in advance: http://steamcommunity.com/app/467820/discussions/3/
If you want to play online while the game's withdrawn from sale, I suggest you subscribe to that forum and/or post in advance whenever you want to do a match. I'll probably be posting there myself, as I haven't had so much time for playing the game for a while. Sorry for the inconvenience for anyone who could regularly find online games before.
If you're wondering why I think the concurrent player count is likely to drop so drastically, it's because the average play time for the game at the moment is very low. The reason there were generally active servers was just because new players were constantly downloading the game and playing it for 30 mins. This is among the problems I hope to address while the game's withdrawn from sale.
-Probably a lot of updates will be less content-based and more boring usability stuff. There are also a few things I need to sort out that aren't direct additions to the game, so there might be less frequent updates too. That being said, more content could address the aforementioned issue with low play times.
Let me know if you have any questions. Remember to subscribe to the thread though if you're expecting a response.
