That's part 2 done. Here's an idea I've come across.

How about Y/N has his own private island based on DK Island from Donkey Kong (mainly Country Returns and Tropical Freeze) and Wumpa Island from Crash Bandicoot (mainly Crash of the Titans and Mind Over Mutant)? 

I feel like just a town, village, kingdom, or whatever fantasy location isn't enough for him. He needs to his own Mr. Beast private island with wonderful yet dangerous landscapes. 

Only on his faction/friends/allies/harem are allowed into this place. Anyone else? Well, they might be asking for a death wish considering that I'm gonna be adding some dangerous monsters and deadly traps. 

Let me know what you guys think at the comments below. Peace out and enjoy!
