Okay so for my first endingof NV I sort of super fucked up . I basically fucked over everyone in the game burned goodsprings , fucked over the powder gangers , joined house then betrayed him except I made a really shitty mistake because I eventually stuck with YesMan but only AFTER I went to bunker hill and destroyed the other securitrons . I like to think that my 9 INT Courier had a severe lapse in judgement and decided to fuck himself over in all his double crossing . It didn ' t effect the ending though but I still look back and laugh at home dumb I was to go through all that trouble double crossing everyone I could just to double cross myself along the way . As for canon endings probably the independent or NCR ending . FO 4 however its sort of hard to tell canon from this perceptive I mean I ' ve finished every ending but I feel like maybe the Institute would be canon ? It just feels weird to spend months looking for your son only to blow him and every thing he ' s built his whole life just because of morally questionable actions .
