Cas,
There are a lot of problems with the scenario.
Ryo has always had a nasty habit of recklessly tweaking things, moving things around, etc., without considering the consequences. I haven't done a thorough check of tax and manpower yet (I suggest everybody combs it through to see what pops out), but right off the bat we have two very serious issues:
1. France and Spain have equal land tech. Traditionally, in a 1492, this means Spain is dead meat. It has no colonies, no exploration done yet, less manpower, less morale and less income. And it's pre-fire, so El Gran Capitan is useless. In the regular scenario and PE 1492, Spain starts with 7 LT, allowing it to vault ahead to 9. In return, the Ottomans also have 7 LT, which is a major part of their early military momentum.
Removing this is historically ludicrous (the Tercio, more advanced Spanish and Ottoman fire tactics and the general superiority of Ottoman troops), but it's also terribly unbalancing. Slows down the Turks during their peak and wrecks Western Europe.
2. Equalized economic techs. This makes life very hard on Spain, the Ottoman Empire and Venice. It's also historically inaccurate and... Well, a gross oversimplification.
Fred just told me everybody's in Latin too. If that's so, well, make that number three. And I'm going to start combing the scenario to see what else is wrong.
You can't just change whatever you want. The game is very carefully balanced (at least at the PE stage of development) and messing around is the best to ruin a game. That's why so many groups that gave Ryo's 1492 a spin abandoned it after just one go.
I seriously hope we're retooling the scenario as needed before we start.
EDIT: And what exactly does "minimal events" mean?
