think about the balance of the game! implementing this in the main campaing would make
of people mad. maybe telling a dev about this for his/her mod?
Think about it this way. In 20 years, would FS2 survive in its current form? Even with upgraded graphics? Now, if it was continually updated and upgraded, including the event lines in the missions, then the story will still sell. Imagine the way

would have created FS2 if they had the technology of 2027 available to them!! The story would be the same, but they would be able to develop it more, to have more (seemingly) insignificant elements to give background. Upgrades that affect mission balance can be compensated for.
Backwards compatibility is great, but I think at some point, (hopefully we will be able to stave it off for another 5 years or so) we're going to have to make a TC for FS1-ST-2, that allows the story to be retold, with better environment, at the expense of being the same as the "official" FS. The official FS should, of course, be kept as another download or mission pack, perhaps with its own engine, but it should not be allowed to drag the new FS down with it, as it meets its eventual demise. (Think: how many people play PC games from the 80s... it is a testament to their excellent design, that any are played.. but they still don't have a big following, because they haven't been updated.
What I'm suggesting is that at some point, we're going to have to take the FS-ST-FS2 missions, sit down with them, and think "what actually happened?", and create basically a flow chart of events. Then, we'll have to think, "how can we add to this, and still keep the same mission story?", and proceed to add or refine elements of it.
While I'm on this topic, let take a shot at the dreaded "Battle of Endor".. Can anyone actually tell me what it was all about? Think.. remember.. use the Force oh, wait, wrong line.. but seriously, people complain about BOE missions.. and they shouldn't. At least, not if it's a
real Battle of Endor style mission.
The Battle of Endor was huge, it was vital to the defeat of the Empire (and thus, the survival of the Rebel Alliance), and it was seriously unbalanced. The Imperial fleet versus the Rebel Alliance. No-brainer. The Rebels must have been suicidal to attempt it. Oh, wait, that's right.. it was a
diversion. They were distracting their enemy from the real battle, fought on the Death Star's temporary shield generator's host planet. The tipping point in that battle was fought by what, 10 people max? They had to get past the defenses on the planet's surface, and destroy the shield generator... then, once their mission was accomplished, the four (?) people on the Millenium Falcon, plus a small (and therefore, easily overlooked) fighter escort were able to fly into the Death Star, and unbalance the reactor (by destroying some piece, I dunno what it was called... probably cooling, most reactors don't take too well to the absense of a cooling system, as the Russians found out at Cherynobl).
If that was FS2, Alpha 1 would have been the Millenium Falcon, or perhaps the flight lead for the fighter escort. Mission is simple, yet deathly complex: keep a low profile and stay alive until your teammates exploit the critical weakness in your enemy's protection. There you go... BOE missions aren't all that bad after all, are they?
OK, when is my execution scheduled for?
