Adagio, I don't understand you. Or rather, I understand you partially. You're almost indifferent to this game; it will be released when it's released. If it's good, it's good; if it's bad, it's bad.
At least, I'm already satisfied with it, if only because it has a Faction that I've been waiting for in the series for almost 10 years.
Adagio, I don't think they'll close access on the 28th. Firstly, by that time, you can already complete the rather limited number of maps that are there. Secondly, the game requires you to enter the key twice: when downloading the file and immediately after installation. Therefore, if someone somehow extends the key, and someone doesn't, the system won't be able to distinguish between these two cases without additional tricks.
