Many video games now have DLC that don´t add too much or are simply one thing that could be in the game but is selled "apart" like the ignis story in final fantasy XV or anything that EA make
Well it depends. For example, DLCs like in Witcher 3 and Skyrim are worth and I would buy them everytime. I think small dlcs like cosmetics are okay, but not if they release one every month apart.
