Borderlands 2: Tiny Tina's Assault on Dragon Keep

This expansion is the best Borderlands content released to that point, both in playability and wit. Its fantasy-themed campaign turns a deliberately derivative kidnapped-princess plot into a self-aware inside joke packed with Lord of the Rings and World of Warcraft references, plus clever live environmental transitions driven by the in-game D&D session. The new weapon mix is unremarkable and going solo at max level can be punishingly deadly, but it remains a witty, entertaining 10-20 hour romp.
