The bonus for vapes is you can wean off nicotine at a super precise rate. You can mix your nicotine juice with more and more non-nicotine juice to achieve greater and greater levels of dilution until the nicotine dose you’re taking is so low that it doesn’t matter to stop.
The game itself isn’t ripping off anything. Pokémon is such a direct “rip off” of digimon, too, then. Except it doesn’t matter, cause that’s what stuff is. Stuff is made up of other stuff and oftentimes there will be similarities!
