This article is and should be accurate for any version of the game.Practical knowledge is a concept that represents the nation's experience in engineering and construction of each particular field. Increasing practical knowledge is done only through production. Otherwise, practical knowledge will decay over time. Practical knowledge has two effects in game:. Modify time (for technology that depends on practical knowledge). Modify the time it takes to produce unitsEffects on ProductionPractical knowledge affects the time and cost of producing things.

It is not a linear function; that is, having a practical of 50 does not reduce building time and cost by 50%. It is approximately defined by a piecewise linear function with the following segments:FromToBonus per practicalPracticalBonusPracticalBonus0-50%50%10.00%50%65%5.00%%1.25%1314.2%2523.3%0.8%2523.3%9048.8%0.4%9046.4%9948.6%0.2%The chart below illustrates the effect of practical on production. An approximate fit would be:. Linear regime (below 5 Practical): +10% time and IC per point below 5. Square root regime (above 5 Practical): Time and IC reduction of 5%. sqrt(Practical - 5).Therefore, a practical value of 0 means that the time and IC cost to produce something increases by 50%.

Meanwhile, a practical value of 10 creates an 11% reduction in the time and IC cost.Practical Knowledge TableBy taking a quick look at the table, one can see that the game designers intended for most costs to be around 1,000 IC-days per practical. For those fields that do not fit this norm, one can see that the designers strove for all units in that category to have the same cost. Some fields, due either to low cost across the board or to low cost in a single unit, are easier to acquire experience in.The easiest fields are Militia and Rocket, being about half of the 1,000 IC-days baseline cost. Massive construction of Flying Bombs and Garrisons will lead to an enormous explosion of practical, quickly cutting production time and cost. Rocket Artillery is also a relatively cheap way of increasing Artillery Practical, being significantly cheaper than the next cheapest artillery unit in terms of IC-days per practical. Interceptor squadrons are the quickest way to increasing Light Aircraft practical.

Motorised Infantry is somewhat cheaper than the next most costly unit in the Mobile Unit field.

Reviews“Hearts of Iron 4 wields complexity like a swift armor division during the blitzkrieg, allowing it to serve the idea of layered, cerebral, strategic warfare instead of letting it needlessly bog down the experience.”9/10 –“It captivates me because—imperfectly, impressionistically, and perhaps a little amorally—it lets me orchestrate the most titanic armed struggles in history, from the fussy economic details to the cut-and-thrust of mechanized warfare. There are other great strategic-level wargames out there.

But I have never played anything like Hearts of Iron 4”8.8/10 –“For now, after many dozens of hours, I'm taking a break from Hearts of Iron 4. Not because I'm sick of it; quite the contrary, in fact. What I need to do is some serious reading, some careful planning on what my vision for the United States should be in 1936.

And when I've done that planning — when I've formulated my character sheet, as it were — I have the utmost confidence that Hearts of Iron 4 will be ready for me to play a role in world affairs.”8/10 –.
