Sincere "nostalgia" for - or rather, familiarity with - the games that are already out, uncertainty about whether or not it'll be actually good is seemingly lower than with XV, plus the campaign so far seems to have sold it as a more focused product (which possibly stems from the fact that this is a singular product rather than something that has been split into multiple pieces like XV). At least, that's why I think some people tend to love it more than XV.
