If I had to nominate a big budget series that I always play and enjoy, despite its mainstream shortcomings, it would be Assassin's Creed. The main thing I love about the series is how much detail and effort is put into recreating the cities and time periods of each instalment. There's an epic quality that's only within reach of the big budgets and big development teams, which often makes up for the cookie-cutter gameplay and story.
