If we completely disregard story, the Saints Row series more or less improved greatly over the course of its 4 games last gen. Saints Row, was completely and utterly GTA clone dujour. Saints Row 2, was an open world crime game with several diverse and entertaining activities and storyline the player could get into without having played the original. It had a diverse cast of rather interesting people to play with and is one of my top 10 games. Saints Row the Third, was a huge let down for me personally story wise, before we go on, stop, stop trying to tell me Saints Row games were never about the story or the characters, saying that only proves to me you didn't play 2 all the way through. Mechanics and gameplay wise, it greatly improved on the formula and was quite enjoyable about 8 months later when I stopped giving a damn about the terrible plot/story elements/characters being nicked into the ether. Saints Row 4, is essentially the ultimate conclusion, based on the Johnny Gat Clone DLC, the super powers were a godsend in terms of changing up the game, it faltered at times by forcing you back to a "human" state for seemingly no reason to "up the stakes" but had a cast of characters that were more or less likeable, gameplay that was nearly the pinnacle of open world crime based game. And, well, it had Professor Genki 2.0, which was also pretty damn hilarious. All in all, Saints Row was, in my opinion, a series that grew and evolved with every iteration, even if the dev team were phoning it in a bit during development interviews and going for a "Zany" feel, ignoring the fact that the charm of 2 was that it was "weird and insane" in a setting that demanded seriousness.
