>>93171961Viewers arrive to a stream for a variety of reasons. Few viewers (outside of mods and VIP chatters) know the streamer outside of twitch, and so little can be said about viewers really being there for the actual vtuber. Twitch viewers are what you might call "the twitch audience". These viewers can often overlap to "the YouTube audience" but there can sometimes be some difference. For example if you are a dual streamer, and you stream on both twitch, and YouTube you might notice the majority of your viewers switching to twitch. Though over time you might start to see new viewers trickle in from YouTube. YouTube is a more global audience. Twitch though having an active viewerbase might not exactly be the most globally available platform for viewers. For example many devices that have a YouTube app available don't have a twitch app available.
So you ask "are viewers there to watch vtuber?" the answer is often yes, and no. Often first, and foremost a viewer is there to support a platform. If viewers were there simply to support a vtuber the vtuber could throw a live event, or switch to a alt tech platform like Dlive, and all their viewers would show up. Alas that is simply not the case. Many viewers are fans first, and foremost to a platform as a platform makes content available to them with convenience, and without ever having to leave the home. If you are vtuber reading this I am sorry, but if twitch, or YouTube went down the majority of your fan base would likely not follow you to an alt tech program as it would be inconvenient.
So the original question is "can a game category attract viewers" to which the answer is "yes". Same as a platform can have an audience so too can a category. Unfortunately popularity fades, so there's no concrete "when stream this get this many viewers" hack.
I can tell you that after e3 presented fallout 4 on twitch I streamed fallout 4 on twitch at 12:00 am my time after renting it from a Redbox on the night of release, and I got 5 viewers. I know that doesn't sound like much, but for 8 years I've averaged 0.2 ccv on the regular, so 5 viewers is quite a lot.
Streaming games that are popular on the night of release is a way to attract new viewers. Though it can be costly to the point you're better off paying someone to watch your stream if all you want is numbers.
Another example of when games can attract viewers is when a game shows up in sales. For example there was this card game called "Hand of God" or something like that, and back when Xbox was pushing that game with their "games with gold" program I got about 15 viewers with that, about 30 viewers with the Sherlock Holmes game that Xbox was pushing at the same time. Point is games, and game categories can indeed attract viewers. We like to think viewers are absolutely devoted to vtubers like old married couples, but really that's usually just mods, and VIP chatters. The majority of viewers are a free people, and wander to channels for their own reasons, and wander away just as easily. Anyway I hope I brought some things to your attention worth considering.
Consider streaming a game that you would want to look up gameplay of.
