A few questions...

[Asmodean]

I put these on the general forum, but realized that they really belong here:

1) Is it possible to speed up Wonders, by lumberjacking, or will nothing speed up the building of a Wonder?

2) If you change the rules in the .bic file, does this apply only to new games, or to saved ones aswell?

3) On the science screen, some improvements are x'ed over with a red x. What does this mean??

4) Will Great Leaders emerge from battles with barbarians, or only from winning battles with rival civs.

Answers greatly appreciated.

1) Only great leaders will speed up wonders.
2) don't know
3) These techs are not required to advance to the next age.
4) Barbarians won't give you great leaders.
