Considering some of the crap that has been green lit over the years, I would bet that Aces High, which has a near 20 year track record and a recent huge update, with very regular fixes/etc to that update, will get the Green Light. It comes down IMO to how much attention that can be grabbed, and how many players from Steam can be attracted to try the game, NOT if it gets "in" or not.
I'd really love this to work. Something to work. It's hard to accept that the game had such full arenas (I remember loudly swearing nightly trying to join orange or blue when my squad was in there and the server was full - 1st world problems right) not that long ago, and that the game is vastly better now, with great VR implementation, etc. With even MORE players interested in WW2 gaming - look at all the WW2 multiplayer games out there - the thing I keep circling back to is these players just don't KNOW about Aces High. Yes, IL2 is great, yes DCS is great, but AH is still a unique experience and game, which can offer a larger sandbox/environment and a scoring system those other sims don't have. A lot of gamers are competitive, and it's that competition and how it can be expressed which should be hammered on to the potential Steam gamers.
Just my opinions, I understand it's easy to have low expectations from Steam, and everything else, but I still strongly believe there are more WW2/Sim gamers out there than ever right now, and that AH can capture enough to bring back those Titanic Tuesday type numbers, and reasonably quickly too. The word - the right word/videos/whatever - just needs to get out to these potential players.
