Note : I wanted to post more but ran out of time. Here are some real answers :
Surviving Mars : it needs a decent computer and mouse. As of now they're still not hooked up (it'll be soon, though)
Factorio. Okay... Not really true : I played through the demo. I'm sure I'll like it. But that's the entire problem :it's the sort of 'one more thing to do' game that keeps you playing much longer. Plus : build something complex and get back to it after a few weeks and you'll have to relearn what everything does.
As such, I've held off buying it (okay : it never on sale helps in that regard)
Castles of burgundy: I love digidiced; their interface is the same amongst all their games, and their games are great. On top of that, this is one of bgg's best ranked board games.
... But at this point, my interest just... Isn't there for some reason. I'm usually sold on a single hook or core idea of a game, which this game doesn't has as much. It might be a known designer's best game, but it's about rolling regular dice and assigning them in slots for... Castles?
Link's awakening switch : an obvious one... I don't have a switch. It'll be the first game I play once I get one, but at this point I just can't spare the amount of money for a new console /hybrid.
