This is the tip of the iceberg.

4) I have been thinking about the manner in which other items are fixed by TURN instead of DATE. Not only would buildings need to be looked at for balance if there were a manipulation of the year/turn ratio, but so too would the impact of more unit production, and also money surpluses. Since a surplus is based on the end of a turn and unit production is also, increasing the number of turns significantly ups the quantity of these two resources in relation to the end of the game and given dates. While your merchantmen will now die more often, you will also be earning cash faster per year and build up experience more than once and rather quickly. While it will still be the same number of TURNS to get somewhere on foot or by boat, this will also happen faster in terms of historical dates and the end of the game...

A .50 game would mean 900 game turns compared to 225, and surely there are other things that fall in category 4 such as the impact of more crusades or jihads, more conversions and so forth I have not thought of...
The biggest problem occuring here is, that you can have your best units at about 1140 (or even earlier, if you really want to) if you are using the .50 time scale, making it 120 played turns and still 780 left. As it is no problem to change the descr_events.txt in order to get the events earlier (e.g. black powder invention, I don't want to wait for the next 400 following turns while running around in full plated soldiers) by halfing the counters it would not make sense doing this, because than you could leave everything as it were before.
As M2TW does not have its descr_*.txt (beside the campaign files) in its data folder or elsewhere (like in RTW), I wanted to ask if anyone knows how to extract the .pack files in the packs folder as I guess these files are included there. Just renaming the extensions in order to extract them with a commen extractor does not work. So you could change the building times for buildings for having a more realistic and longer game experience.
