The other alternative to slowing the minors down may be to just increase their tech costs relative to majors. The readme for Real 2.0 reads:
I'In order to avoid small nations being the most advanced in research, their research costs have been raised. They should now be roughly at the same level than major nations. To achieve this , monarch values have been lowered.'
I don't think this is necessarily the best or most efficient approach. Rather, just upping the tech costs for minors should do it and that way the variance in MOnarch effects (which are very interesting and add a twist to the game) would be kept intact. My suggestion would be to avoid restricting ranges in monarch effects and allowing the tech costs to do this. This allows for differences between minors to be reflected better - removing extreme values for minors on monarch values effectively makes for more vanilla play.
True, but I think the issue Laurent has is that the Monarch rating influences the tech investement - i.e. a higher rated monarch adds ducats to the research, and over time that has a negative affect on the game. I have not heard that the tech costs can be manipulated via configuration files, so I presume that the only manipulation available is the monarch ratings. Given that monarch ratings are relative (mostly), manipulating them could achieve the desired affect without distorting other factors.
I have done a random walk throught the monarch ratings (in IGC), and generally, they are pretty high for most countries. The other trend is that for 'historically marginalized' countries (for lack of a better term), they are pretty generic, and only the Diplomacy rating (which does not affect tech research) is high. So, I contend that one could decrease all monarch ratings in a way that maintains historical fidelity, in relative terms, while achieving the ends that Laurent is pursuing.
That said, I am speaking in a theoritical sense, since I have no direct or imperical knowledge of how the game system works other than limited play and from reading posts from experimenters.
