Real dark patterns are parasitic. e.g. loot boxes: players would rather just buy the items directly, and even if they end up spending more on the loot boxes, they’re not happy about it.
When a player says “I’ve wasted 1000 hours on X game and I love it” (e.g. Factorio), it’s a good game with addictive mechanics. When a player says “I’ve wasted 1000 hours on X game and I hate it” (e.g. LoL) it’s a bad game with addictive mechanics. Now those games blend the lines - if a game gets too addicting it probably starts negatively affecting you either way.
