Eh. I guess I'm in the minority here but I really liked the slow movement of sliders. As others have pointed, these are not only goverment iniatives but cultural markers as well, and you just dont go from a Prussian tradition of an excellent office corp to an English tradition of giving great prestige to the Navy in a decade or two. Ditto for the religous tolerance of Bohemia, or the intolerance of Spain.
The sliders force you more or less to take a long view and stick with it. To take one example, it seems to me as France you can choose several strategies: colonization (narrowminded/navy/free trade) making a sprawling continental empire with lots of "wrong" religons and ethnic groups (land narrowminded serfdom a little decentralized) or sticking with one religon and building up an economy, tech (centralization innovative free subjects.) The point of course is that you have to make the call fairly early on, and you can't easily switch even if things go badly at first. Under a more loose slider settings france could say, spend some time gobbling up colonies and then fairly easily transition into a different strategy with a decade or two. I wouldn't like that as much, theres less of a long term plan and the challenge of making it work and less of a tradeoff.
