The problem with mmos and villians is that the heroes or so called player characters cant loose so there is zero feeling of threat anymore it's just the next big bad after the next and we stomp them all with borrowed powers or help. They had the chance changing that in sl with the jailer winning and remaking reality but nope he was stomped easily enough in the end like all the others and you already know they are going to loose.
His arc was also pretty much thanos with the stones too so not interesting at all and in the end all we got was again that there is a even bigger bad coming.
