>>197629311 is way harder to achieve, but is pretty consistent in viewer retention since good plays are always amazing to watch.
2 is pretty easy to achieve, just pretend to be retarded while spewing monke noises. Give good numbers for the first stream but will fall off hard if repeated excessively since people just get bored with the monke noises and get frustrated in watching the bad plays instead.
If you're a variety streamer, go the 2 route. Just get bunch of games where you can make monke noises at, rotate it and you will always keep high numbers.
If you're already at the 1 route though, it gives consistent high numbers without the need to reinvent yourself or anything, so in a sense it's a comfy route.
