The only tech I would rush would be Military, and that's more of an early game thing. 10% all powers reduction is just too good). Tech is the largest mana sink in the game so sometimes it does make sense to fall behind (well, not anymore now that innovation exists. It's better to spend monarch points on devving than let them go to waste because you're hitting your cap, but often there are other uses for them that give you more significant benefits in the short term, such as boosting Stability, coring provinces, integrating vassals, reducing War Exhaustion, or spam-recruiting Generals to increase your Army Professionalism (rather than wasting Ducats turning your army maintenance on to slowly drill troops). For singleplayer, however, it's much less important, though still useful. Sure, picking up that juicy Military tech 10 years before everyone else sounds nice and all, but unless you really need the advantage to swing above your own weight, you'll likely be better off waiting, saving up your mil points and spending any excess on breaking fort walls, scorching earth, and so on, as well as devving occasionally so you don't max out and waste points, until the ahead-of-time penalties are gone or miniscule - your country will typically end up stronger for it.ĭevving provinces is extremely important for competitive multiplayer, where the solidly established meta is to expand until you reach agreed-upon borders with nearby players, and from that point onward play ultra-tall, minmaxing the crap out of every province you own. However, taking techs ahead of time is not always the answer. They are your next best way to improve your power level, after all, not to mention that Admin tech is needed to unlock new slots for more Idea Groups. When Ideas aren't an issue, however, technologies should be your next highest priority. The only scenarios in which you should prioritize tech over ideas are cases where you absolutely need equivalent military tech (or a military tech advantage) to win a war. Ideas are the most important thing to spend your monarch points on, not only because they provide substantial boosts to your country, but also because every Idea you unlock in an Idea Group reduces the costs of all future techs that use the same type of monarch point by 2%, saving you more points in the long run - so, for example, unlocking every Idea in the Administrative Ideas Group will reduce the cost of all future Admin techs you research by 14%, on top of the 10% cost reduction that's included in one of the Ideas in the Admin group.
