@patrik said in Atomic bomb - the Wunderwaffe: I think this corresponds to the real scientific process, where more investment over time increases your chance of succeeding, but there is always a good portion of luck. Scientific progress is very random. It is very likely just pure chance that we have a coherent theory of general relativity (Einstein managed to get it right at the first shot), while after nearly a century we still can't say the same about quantum mechanics. Or to take another example, the amount of evidence for heliocentrism over geocentrism was basically the same at the age of Ptolemy as at the age of Copernicus; it could just as well have become widespread in the ancient world a millennium and a half earlier. Technological progress, on the other hand, is very different. I wouldn't say there is any reasonable amount of luck involved in developing a particular tehchnology. The reason it seems random is because we can't tell in advance how difficult exactly a specific problem is, and also because it is hard to assess how effectively your engineers can work on the problem given the funding they get. Real life set aside, if someone can possibly get this überweapon round 3, and your opponent only gets it like round 7, then he will feel RNG-f***ed. (Quite rightfully so too.) In principle your strategy should be prepared for randomness, but I have doubts whether or not "roll a dice, if you roll 1, you lose"-type randomness is good for player experience. The tech system itself is a great idea though. You could have easier and harder technologies. Also IMO it is much better than most other TripleA tech systems, because you can go from "very slim chance of getting tech" to "almost certainly getting tech" by just doubling your investment, so there is a very real tradeoff between PUs and chance.
