As I've said a few times, I think we're misconstruing what they're saying which is that the mainstream gaming community will snap it up and buy it on release, as well as folk like myself sat on the fence, and I'm not a massive Chris Roberts fanboy but they may have a point (note the stress on may) when you consider how 'mainstream' by the standards of it's time Wing Commander 3 was.
It's this whole topic that I find weird/interesting - the assumption (or hope) that there will be a wider audience for Star Citizen and/or SQ42. CIG have already taken ~$250m in pre-orders* for their games which, I imagine, is a very large chunk of their target market and all of the pre-order/1st week purchase crowd.
The days of Wing Commander 3 are very, very over. The gaming world has changed massively. WC3 is 25 years old. PC ownership demographics are vastly different now - back then PC ownership was still very niche (I know - I had one, a vastly expensive 386/33 machine with 4MB RAM, 100MB HDD that cost as much as a used car when I bought it in 1992) and nerd-driven, so space games esp ones that tried to do something new - cinematics - had a wider audience** in that pool. CIG are offering nothing new, Planetside 2 does large-scale FPS fighting, ED has the flight model & trade, and single-player FPS space games haven't exactly done the numbers that their publishers hoped for.
Bar the few people sitting on the sidelines waiting for a finished product before purchasing, I can't see a market for SC/SQ42 on the PC. It's already been saturated. If they're potentially looking at consoles for a wider audience then that's very, erm, brave of them.
I don't know. I just think that CIG have put themselves in a cleft stick with their business model.
EDIT: Apologies if waffly. Thinking out loud, so to speak. I just think that CIG are screwed if they actually release their games.
* $250m is over 4.1m copies of a $60 game, just to put that figure into context wrt sales of AAA games.
** I played WC2. Didn't get on with it: I thought that the story was simultaneously both overblown and dull, plus the actual space combat kinda sucked. I was an avid RPG/tabletop gamer, Scifi movie & book nut so perfect audience for the Wing Commander series. Oops.
