While the new classes and focused narrative are the marquee bullet points when it comes to this sequel's improvements, that's barely scratching the surface of the multitude of smaller upgrades. Inventory management and the user interface are much better, allow for simple buying, selling, and comparing of items.
All of the improvements would make for a standout title even if it were constricted to single-player. Considering Gearbox has continued to put this franchise in a league of its own when it comes to co-op, it elevates the game to something more. With its unmatched co-op gameplay, intense shootouts, addictive loot-collecting, expansive skill customization, hilarious dialogue, and insane level of replayability, Borderlands 2 is one of the most rewarding experiences of this console generation.
