FS2 has a few mission errors. It doesn't use many of the new features that the team has implemented, and simply putting them in there would change the missions.
So, consider this a test of the waters. How would people feel about playing 'remastered' FS2, with the same story, characters, missions etc, but rebuilt to a) use all the new features properly, b) retain balance (although, maybe fix the easyeasyeasyHARDeasy nature of the campaign).
I appreciate that changes would be slight, and changes to the overall feel of the game are to be avoided, but when the old FS2 campaign looks like ass next to our campaign authors work, it's time for a facelift.
To go further than bugfixing and updating, the capabilities of the engine are massively superior to the release engine, and many missions could be improved by a general increase in scale. First, though, I'd like to see if people are religiously attached to the original untainted FS2 campaign, or if, like the classic Derelict, it's time to take another look.
