Well, with the new variable handling Sexp's from the SCP, it should just be possible to keep score and end the game when one team has scored 5 goals, the football game could almost be done in Vanilla FS2, but you'd need some nice animated glow maps on the ball etc for it to look 'right' in my opinion.
The CTF thing would probably require some specific coding, which may or may not be possible, once the SCP guys are a bit less busy bug squashing, I'll put a query in the SCP forum, though I have a feeling this would be pretty tough to do since FS2 wasn't designed to handle this in any way, possibly something like 'instadock' when you are less then 5 metres from the ball or something?
