Is it just a coincidence that the Wing Commander series died with the Wing Commander movie?
Just coincidence... Really. I mean, the movie makes a good excuse but it just didn't happen that way. It didn't help, but it didn't really hurt it either, except maybe in the minds of people who had never played the games anyway.
To some degree the series was a victim of it's own success. Not only had the series creator gone off to create his own studio (that did the films effects work) EA became increasingly unwilling to risk the large budget price on a genre that was dwindling. That's why Wing Commander Prophecy scaled back the production costs from Wing Commander 4. It cost a tenth or lest of the cost of WC4. When numbers of sales on other space sim titles fell through the floor (Freespace 2 for examples) that was more than enough reason... sort of. Privateer 3 was even playable and was cancelled the day before they were supposed to do the film shoot.
The other contributing factor to the disappearance of Wing Commander was actually Ultima Online. It was *so* successful that EA - dissatisfied with the way Origin had been leaking funds - pretty much made Origin the Ultima Online company. This is where it gets wierd. During the time period of the movie's release, EA pretty much had Origin shift all their development to MMOs essentially. For a while it was Wing Commander Online. Then that Became Privateer Online - TWICE. That's right. There was at least two different attempts at Privateer online, and that was *AFTER* the movie came out. Heck there was almost even a Wing Commander TV show twice upon at time (after the film came out) that was being developed after the initial episodes of Enterprise came it with such strong viewer numbers. The reason a lot of these projects died were numerous and didn't really have anything to do with how well the film did.
I see a lot of direct parallels with Wing Commander. It wasn't the Wing Commander movie that killed the series. It was when Origin started putting Mark Hamil into the role of the protaganist, removing the generic pilot (that you could name) and the whole "the hero is you" bit that a lot of people liked. This desician, and other ones cannonballed the series. If you believe the hype and a lot of reviews these games were going strong and you'd be justified to wonder "WTF happened, it must have been the movie", but if you were part of the fan base at the time, and on a lot of the forums and stuffm the players were actually fairly against what was going on, including changes to the gameplay to make it "more realistic" in the way ships handled and so on. Origin went right ahead to play with their celebrity actors and big movie productions, and the fans eventually decided "nope, not anymore. You know we made two previous games sell well that weren't what we wanted due to loyalty, take these last ones and stick them where the sun doesn't shine".
Chris Roberts fully intended to get into the film buisness. His movie making aspirations are evident even in WC2. Prophecy sold just fine. WC4's budget really ate into the profit margins of what was a really successful game... enough for EA/Origin to shy away from that kind of investment. What worried them was that fans of a WC6 or 7 would demand that same level of investment and they just couldn't justify it. So prophecy was an attempt to prove that they could do it for a fraction of the cost.
