I don't get how anyone on this forum, who follow or have followed multiple MMOs through development, could be even remotely concerned about the amount of time this game seems to be taking. Anyone who could be assed to do it can find reams of data about the progress being made, more so than any other MMO in development I've ever seen. More than that, you can play elements of the game as they're completed; Arena Commander is more fun with more options as each patch releases - currently 25 flyable ships with the ability to customize their loadouts. The new matchmaker in the current alpha allows you to team up with friends for squadron battles, you can do races, you can play against AI or players.
Why do I mention this? Think about another large budget MMO that recently came out - ESO. What could you do in that game 2.5 years into development? NOTHING. You didn't even know about it, because they didn't even announce anything until it was 5+ years in development. Let's keep in mind that after 5 years of development, they were already 100 million+ in the RED. Add to that another 2 years of redoing shit, and they were really in trouble monetarily by the time they released, so much so, that much of the original vision was compromised because the guys holding the purse strings started to make the calls. SC doesn't have that problem. They are still in the black - everything they've done so far is paid for. They're still making consistent money on a month to month basis, even with fan burnout. When Star Marine launches, the funding malaise you've seen in the last month will be lifted - mark my words. Forget Star Marine, though - think about when multi-crew drops in the near future. People actually able to play on each other's ships and slug it out with other large ships? People are going to be excited and willing to spend even more. Let's not forget Squadron 42 coming out. This game isn't just an updated Wing Commander; it's more like a cross between Wing Commander and Mass Effect and Unreal. A lot of the people who want that game already have it - this is true, but I think there will be a larger audience that will want to play it and will based on reviews, footage, etc. Let's keep in mind that EVERY additional sale is almost pure profit - The game is paid for already. There's no publisher to take a cut of sales.
So, if you're worried about the time frame, you shouldn't be, for two reasons - (1) MMO's take a while, and (2) the funding is NOT drying up anytime soon, with one caveat - progress needs to continue to be made and displayed.
