No, it was a complete accident while screwing around with magnetrons
Ah, so you're right, but you're still wrong where it matters. This Percy Spencer fellow was testing a magnetron developed to be used on radars; testing it to verify that it functioned as expected. He was in no way trying to figure out what other esoteric uses microwaves have - he was building and testing magnetrons for a very specific purpose, and happened to notice that his candy bar melted. So in this case, radar research led to a major technological breakthrough in heating food. The only similarity is that both things involve microwaves (but they involve them in very different ways) - and such fine distinctions do not make it to the surface in games. In a game, that magnetron research Percy Spencer was doing would probably be called something like "Radar +4" - it would seem a little odd to be looking at a research tree, noticing that "Microwave Oven" comes after "Radar +4", right? That's that progression was accidental. And blind or semi-blind research can emulate that to an extent, where it would simply look ridiculous in a fixed tree.
One of the reasons for this is that research in games tends to be result-driven, not method-driven. In a result-driven research model, you research things like "Radar +4," which makes your radar better, or "swords +3" which makes your swords better, or "gunpowder" which gives you the ability to make and use gunpowder. In a method-driven model, you'd research things like "microwave physics", which could then be applied to improve the magnetrons in your radar, or to make a microwave oven, etc. I have never seen a full-blown method-driven model, although some games (Civ IV for example) are a little bit mixed.
Heh? I know this is the internet and people love to argue, but I don't see why this is a case where I could be right or wrong? I simply indicated that the guy I quoted was misinformed about microwaves. I hadn't read your response yet, which is a pretty accurate representation of what happened *I skimmed through and saw other responses that had nothing to do with radar/microwaves*
However I agree with having a somewhat blind or random system. Just like a good game of euchre or poker you can often win when dealt a poor hand if you know how to play it right. So the "Getting RNG screwed" complaints don't bother me, after all any tech advancement is an improvement over what you had before.
However, I think this game will be more about create ways to IMPLEMENT you tech than just researching the best stuff. The microwave oven's creation would be a good example of this sort of thing... Someone researched and created magnetrons and they were being used for RADAR... Then some guy is like," HEY this makes things hot!" and uses it to cook food.
It could be that way in Elemental, too. Through whatever research method the game implements you discover how to imbue things with a fire element.. Do you imbue weapons to cause searing heat to inflict more damage on your enemies as would be the first instinct, or do you find a more creative use, perhaps you can teach your farmers to use it to keep their crops warm year round and produce more food ..
