The idea of a "platformer" game doesn't really exist anymore, outside the niche pixel side-scrollers on Steam. A lot of the old "action/adventure" hybrids like Metroid and Mario and Zelda have been replaced by over-the-shoulder open world games and shooters. Hell, Metroid probably would have been shooters at inception, if the tech had been up to speed. Games like Contra tried to be on certain levels. Meanwhile, Zelda and Mario have really come into their own after M64 and Ocarina thanks to the open world style of play.
The modern idea of "adventure" is more intended to describe an exploration game with RPG elements, rather than a story-driven platform hopper. I think that's probably truer to the intent of the original game concept that "adventure" games were intended to describe.
Should be worth recalling that the original intent of NATO was to prevent German industrial machines from combining with Russian extractive industry. Now its sort of a moot point, since China has replaced Germany and the US as the industrial workhorse of the world. Perhaps if the Sino-Soviet split had ended sooner (or had never occurred in the first place), the USSR would still be standing and the Americans would have been the ones to collapse in the late 80s.
