AnswerThey're just as old as the the Space Marines because 40k stated with Space Marines vs Orks.
Yes If you find the answer insufficient, please elaborate your question.
Whether 40k Chaos Space Marines are better to collect than Orks depends on personal preference and playstyle. Chaos Space Marines offer a rich lore, diverse unit options, and customizable armies with a focus on dark themes and strategies. On the other hand, Orks provide a more fun, chaotic gameplay experience with a unique aesthetic and a focus on sheer numbers and randomness. Ultimately, it comes down to which faction's narrative and gameplay appeal more to you.
you take the role of space marines (a superhuman genetic warrior and fight chaos daemons and chaos space marines and orks i dont know the storyline but thats what happens
Technically you can play any army against any army, and any army with any army, except where rules specifically state that you may not (E.g. Black Templars may never ally with an army containing pyschers) It would however be extremely unusual, but so long as you have a good background story, it should be fine.
