The complexity and variety of the weapons, as well as the different monsters and the personalities is what I like about them. It's basically a boss rush game with the occasional gathering session for environmental resources.
It's not a game for everyone, and it's kinda a running meme that everyone drops it shortly after there first time playing it, only to come back years later and get completely hooked.
If you do decide to try it, I really suggest messing around with the weapons in the training area until you find one interesting to you, and then searching up a guide for it.
Performance definitely leaves something to be desired and will hopefully be better at launch, but other than that she is fun. I like a majority of the changes on the weapons with the exception of completely removing the air bounce combo thing on the insect glave. I get it at the same time though, a majority of Monsters can't even hit you while your in the air.
