Dawn of War: Soulstorm

This is the not-so-well received 3rd expansion to the very well-received game Dawn of War. It adds the Dark Eldar and Sisters of Battle races, alongside terrible flying units. It is riven with terrible bugs (including some that make whole factions unplayable), glacial loading times and typos.

On the other hand, it has some hilarious dialogue. Memes extracted from Soulstorm include Baldeale, METAL BOXES, SPESS MEHREENS and more.

All that aside, it's still quite fun to play.
