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.

You’ll need some kind of internet to download the ISOs for whatever version of Linux you chose though.
