Lydia, the Beast vs Man of Convenience

Has a game ever frustrated you to the point of breaking things? Yes? What if you couldn't quit? What if you had to live out that scenario, no help, no nothing? ------ This idea came to me after a few glasses of wine. The game in question is ck2, if anyone is curious. Now, hear me out here. There will be a syste- wait, why are you leaving!? It will NOT directly influence mc's power. This is not a fantasy world. No fancy magic, none of that. It won't secretely turn him into shrek or hulk either, appearance wise or otherwise. It will simply chip in on matters of convenience, i.e. provide a cheap knife (no it won't randomly turn into excalibur) or some jewelry or some slight knowledge or expertise on whatever mc decides to buy from it (no, he won't become a sword deity, ever. He won't become a master chef from one buy either.). It is truly only there to provide him with some advantage so that he can actually have some impact. The mc is not dumb nor a genius, nor does he have amazing skills in anything (he does have a little something something to spice up his background though). The game also does not provide him with any in-depth knowledge of the future, as those who know ck2 will understand (just because the nun you, innocent poor bastard, let in in goodwill turns into thanatos and wins every game of chess before murdering you appears in one timeline, one crash to desktop later, and the nun might not appear at all). If anyone reads this, I gladly congratulate you on wasting your time. Chess is a great game. Ok. Bye.
