Which is why I added "in theory" and "possible" into the sentence.
Even reaching the $5 million mark doesn't 100% guarantee that the game (SQ42 or the MMO) will ever be completed. Robert is definitely aiming big, in his funding goal and what he wants for the game. There is a lot that can go wrong, which means there is also a lot of room to disappoint.
I've also seen today that Valve
might (someone heard from a friend who has a friend who knows someone at Valve
type whispers) be working on a privateer like open world space sim. If true and Star Citizen gets off the ground, it would make this niche's landscape quite interesting for the next two years.
