Earthbound did that thing with the final boss. A pirated copy would have more enemies on the screen and it would also crash before the final boss
Game dev tycoon had a thing were the pirated version of the game would be harder as it was coded that pirates would steal the games you make. I thought that last one was absolutely genius lol. You can now toggle the pirate mode in the settings to experience it yourself.
I just hated how he would talk about Fable 2 when promoting Fable 3. I still remember one article I read 12+ years ago, the interviewer was asking him about how fable 3 would compare to Fable 2 & peter molyneux scoffed saying something like “God dont play that. Fable 3 is what I envisioned” and then he went on about how he worked to get the idea of touching others into Fable 3. The whole hand holding thing he kept talking up about how it was the most amazing feature to implement.
You’ll lose access to the game but you’ll still own the DLC/expansion. If you resub on gamepass then you’ll have access to the game and the DLC you owned again.
