Ibn-Khaldun: As much as I know, that and much more was already possible with the strat_ed in RTW. Too bad they didn't include it in the final release. There are traces of a strat editor all over RTW files, along with an edit log that shows what actions were performed and according to that, pretty much anything could be done with it.
On a side note though, RTW Demo exe looked suspiciously big. Wonder if they left something in there..
