Yeah, it feels like scope creep is a definite problem with that game. Apparently they also switched engines at one point as well. This is all reminding me of the stories I heard about the Development Hell of Duke Nukem Forever.
Yeah, they were using the CryEngine, then ditched it and got sued in a legal squabble that lasted something like 2 years.
Personally, I think changing the engine is just about the biggest warning sign of major project management problems you can have. It's going to require massive coding changes. I suspect a major reason is they sat working on the game for so long they decided the engine was out of date, or added so much in that they realised it wasn't fit for task.
This reminds me of a friend I used to play strategy games with. He'd never build a military, because he always wanted that extra tech which would make his military better. And in every (literally) game he'd be crushed midgame by someone who, you know, built a military. We'd do multiplayer co-op Starcraft and have to secure him a new base, because he'd turtle around his start point and run out of minerals before he'd built an army to expand with. Le sigh.
Star Citizen's #1 problem is that its design document is an ever-growing list of "wouldn't it be cool if".
They do apparently have a roadmap up now. It's just (having taken a quick look) I still can't see anything that looks remotely like a release date or something that gives an idea of when a likely release date might even be. Sure, it's nice to know they're improving the throwing objects mechanics... but is that what really what you care about?
