Even if you kept the culture perfectly intact, gaming itself has changed. Players expectations have changed dramatically. You'd need the same culture perfectly adapted to the changing gaming landscape which never happens.
My 8 year old nephew spends vastly more time on very old and Indy games not because their “popular” but simply because their more fun.
In fact Blizzard and especially Activision aren't really well loved company by gamers. Didn't EA got the title of worst company multiple times? They probably have a decent competitor now.
