Niggles: I know its great for watching people playing games, but honestly... whats with some of the streamers just sitting there talking... and people watching them talk? help if its a pretty asian girl....but i got bored of watching after 5 minutes..one talking and all the comments in channell.........
I normally don't watch people play games, at least straight. I HAVE watched videos of people playing games occasionally, but it is normally to save time. If there is a game that I've gotten tired of playing and it has a story, but I don't want to spend the time beating the game, I'll go find a playthrough of the game (hopefully without the talking, I HATE playthrough's with talking). As it is a video, I can skip ahead through the boring parts and really cut down on the time to see most of what I want to see in the game. 100 hour game...done in 4 hours!
Another reason I have gone to see gameplays is if I'm stuck in a tough spot and can't figure out what to do next. Watching someone play through that section can help me figure out what to do next without spoiling the rest of the game. In this instance, having them talk about the game (especially to help me understand what they are doing) can be extremely useful.
Other than that, I don't watch game playing as much, but I have friends that LOVE watching gameplays. I don't exactly understand why either. I had a friend today who has beaten Jedi: Fallen Order twice and was watching a gameplay of it from another person who was playing it. I guess they really love that game. Other than the reasons I listed above, I really don't have a desire to watch gameplays, but I know (as in the case of my friends) that there are those that love watching them.
We all have different things that we enjoy. If people want to watch others play games on twitch (or elsewhere) and they enjoy it, good for them. I hope they have the opportunity to do the things they enjoy in that manner.
Might not be for me, might not understand it, but I'm happy that those who do enjoy it have the offerings available for them to do so.
