OpenAge has been around since 2013 with almost nothing to show for it. It desperately needs funding and developers to at least finish a game engine, and then use that engine to build an Age game (1 game, any playable game).
I imagine that in 5 years, Age2 servers will be too expensive for MS to maintain, the remaining servers may not be enough for competitive ranking games (if there is still a competitive scene). If by that time OpenAge is still an engine, it will go to waste the same way CaptureAge may go to waste now
The servers are the same servers used by the xbox games of the xbox gamepass, which is tied to the console world, so the servers will have a lot of future, problem is that knowing Microsoft they might eventually charge to play online but for now they wont charge.
