To those who say that: Why? Have you played it? Are you aware the game is in active development? It's not like this title has gone dark with zero updates in months. They literally have 3-4 updates per week. Saying "it's not coming fast enough" is not a reasonable reason to cry.
I've played it back when I was a backer. I no longer am. The project is crowdfunded, which means I supported it originally and expected them to honor that trust; they didn't. Instead they expanded the scope to unmanageable levels, kept releasing ship videos, missed all the deadlines they set, kept largely ignoring SQ42 and kept pushing it back for years, sold land on their planets, and used the pre-alpha excuse to dodge criticism.
I cannot in good consciousness support their crappy project and their marketing practices. Also, I strongly believe now that it is a scam.
So it's not "it's not coming fast enough" that's the complaint. It is "it is a mismanaged perpetual crowd funded project, that broke the trust with (many of) its backers, with lies, macro-transactions and huge delays, way - way overdue according to their own words and old (missed) deadlines, missing most of the promised features, having few game loops that are very bare bones, and under-delivering tier-0 implementations".
I also seriously doubt there's some design document leading the development. It's just "here's a bunch of stuff we threw against a wall, now let's focus on this particular bartender AI".
See, it's a bunch of stuff that's wrong, and none of that is that I want it rushed out the door.
Generally keep anything Star Citizen at arm's length myself, but what is Squadron 42? Is it like a bite sized version of Star Citizen that supposed to be fully releasing soon?
It is a campaign, single player (and also supposedly have some missions supporting co-op). Basically think of it as something closer to a new Privateer or Freelancer. It's the one that will feature all the big name actors they advertised and Chris Roberts huge script that he once threw on-stage.
No one really knows how big it's going to be. Or what exactly will be released first from it. They already have talked about sequels / additional chapters (that some early backers already "own"), they have said they would release a prelude or the prologue.
It's as you would expect from this project a mess and mist of promises and thin air.
