Thanks, most of that are things which can be addressed without too much work (i.e. writing new texts).
For the wonder names, even though my linguistic intuition is probably not as reliable as yours considering I'm an ESL person, I think in some cases the "The" needs to be there. These are cases where it's a proper instead of a descriptive name (just "Colossus" sounds weird) or it's a specific building with a generic name. E.g. there are many Great Libraries, but The Great Library refers to one specific library. For most of the new wonders I chose them quite arbitrarily though so I'll give it a look.
