The funny part of all this is that they have been wanting revenge against Jim for quite some time ever since his first video talking about their game was up on YT. It doesn't surprise me to see one of the brothers doing this at all and I actually expect the case to get thrown out because as far as things go, one if not both brothers are acting incredibly childish about the whole situation. We've had Jim review or talk about plenty of games and have devs not file vengeance against him, hell he talked about a game the creator behind Five nights at Freddy's made, the creator took the criticism to heart but instead of getting angsty as fuck he instead decided to go and make FNAF and that in turn became a success for him, without Jim he would still be making fluffy cuddley animatronic games instead of what he makes now.
The amount of money hey are demanding is absolutely insane though, I can definitely see them wanting that much since Jim doesn't make anywhere at all near such an amount and as such they would be able to cripple him, I just don't see that flying at all.
If you don't know anything about this whole ordeal, watch some of Jim Sterling's videos on the subject and read/watch a load to get up to date.
