I'ma be honest. This is something that has always bugged me in the previous Fallout games. There are obvious spots in the game's world where there are pool tables, which seems to be used for playing pool at times (such as in a bar or in an community area) yet we can do nothing about it... Pool balls are pretty useless and pool sticks are used as melee weapons...
Would it be nice to maybe be able to actually play pool at certain areas in exchange for caps? Like make a bet, win the game, and make caps (or lose)? I mean, it isn't too far to have. We had some gambling games in New Vegas and they already feature video games for your Pip-Boy in Fallout 4! So it isn't too far to ask, right? It honestly would be cool and fun in my opinion. Adds a bit more to the world for you to actually enjoy and interact with...
I can't be the only one who has ever thought of this, yes?
