There's no shortage of factions, locales or colorful characters for Creative Assembly to explore. In a Total War game, each of these factions represents a possible enemy or different choice in what civilization the player controls.
Orks, demons, various advanced alien civilizations and legions of humans plus Astartes who've fallen to chaos are just a few. Space marines protect humanity from all manner of threats. Hope rests in the hands of humanity's guardians, the Astarte - Space Marines. Devious aliens emerge from millennia-long slumber to reclaim their planet and squash the troublesome insects that call themselves human. Psychic powers awaken at random in the masses, an accident or fault away from tearing a hole in reality and opening the door for demonic influences. "In the grim darkness of the far future, there is only war." That quote is at the start of almost every novel, game, rule book or other medium in which Warhammer 40K appears. This is a universe in which humanity is besieged from all sides and within, engaged in a desperate battle for survival in this dark future.

Individual hero units can offer support for friendly troops or wreak havoc on enemies. Optimizing an army and learning how units should interact is key to survival and progress towards player goals. A player's enemy is in constant flux from battle to battle, as alliances can be made and broken on a whim. This aspect is inherent to Total War: Warhammer's gameplay. On the tabletop, games are won and lost by a player's ability to coordinate their dominant strategies while adapting to new threats. Total War is the perfect venue to showcase the best aspects of Warhammer 40K. Since then, no video game bearing name Warhammer 40K has simultaneously captures the universe's aesthetic and while delivering the proper scope and weight of actions that define this grimdark universe. Warhammer 40K games haven't hit their mark since Dawn of War II in 2009.
Another game set in this sci-fi universe makes sense.
Games Workshop is always eager to create more Warhammer and Warhammer 40K fans, and it has already done so in-part with Total War: Warhammer.
