Do you really imply that playing the same game over and over again (with some variables but still) is the same as solving programming problems? The game is literally designed to hook you in and make you play one more and one more. You absolutely can autopilot through a game and still win. Don't get me wrong, the guy has a lot of dedication for sure. But playing League all day is really not like coding all day, I don'…
Have you played League of Legends or Dota 2 before? It will be hard to convey the mental/emotional exhaustion that most people feel from playing MOBAs at even a semi-competitive level. In my experience it's a lot different than playing FPS or other games. I have a distinct memory of finishing a game of Dota 2 and realizing that it felt as though I'd just finished a 3 hour exam. I didn't feel happy that we'd won, just…
Not to take anything away from Tyler1, because he really goes above and beyond, but it really doesn't take much mental focus or anything really to play it. Programming? It takes focus, you really have to think sometimes. But League? When I'm tired the game plays itself. It just feels like muscle memory.
It might take a bit more effort to play at a consistently high level. But I'm pretty sure it's mostly muscle memory for him too. There's very little actual thinking other than the big picture of what objectives to take and I'm sure when he's playing for 20+ hours he's just on autopilot for the majority of the time.
To put it into comparison with how little mental power it personally takes me, I like to watch a lot of Anime, that's Japanese animation with English subtitles. I can't watch Anime if I'm tired because keeping track of subtitles and what's on screen actually takes a substantial amount of mental power. But I can bash out 5 games of LoL back to back when I'm equally as tired.
