I wish I knew how fantastic innovative ideas are. Not openly flashy, but it contains arguably the most powerful military bonus in the game (tradition decay). On top of this add reduced prestige decay, cheaper mercs, tech cost reduction, reduced recruitment time, war exhaustion reduction, an extra free leader, and cheaper advisors...yeah awesome. If that doesn't do it for you, innovative significantly reduces MTTH on the agricultural revolution event which can make your country rich if you have a lot of grain provinces. Add the liberte, equalite, fraternite event and I'm sold. Ask your doctor if innovative ideas are right for you!!!
