I wold keep POTC. It sounds like your enjoying it as does your family and friends. It also sounds like you like the skill level of the game and want to see more.
Some of the newer pros can be pretty brutal. I personally love getting kicked in the nuts by a game though, it keeps me coming back for more. My friends and family not so much.
There are no guarantees that you’ll like ST as much and you can always make a comparable trade down the road.
Edit. I didn’t realize you had it for 6 months, so maybe it’s time for a change. I love rotating games in and out. I think a mint POTC is worth more than mint, stock ST, but a few hundred at most. FWIW - I personally like ST better especially if your a fan of the theme.
