[quote=@Terry Bogard] Could be, but what should be the reason why they fight the Reach? [/quote] Because, in the greater universe among civilized spacefaring planets, it is known what the Reach does to worlds. It's known that they go to developing planets who have yet to discover their place in the cosmos, and they fuck shit up. One of the Guardians had a personal connection to this, and when it was discovered that some backwater world had been targeted by the Reach years ago, they decided to act. That's just one justification off the top of my head. If you want to write the Guardians, and you want to base them on Earth in this setting, it wouldn't be difficult to weave them into the narrative. The problem is, though, that I think you'll find it to be difficult to [i]maintain[/i] the Guardians as part of the narrative for long. The conceit of this game means you'd have to have them stick around on Earth, which severely undercuts the entire point of the Guardians of the Galaxy. It's not just about having a character concept that can be woven into the narrative, but having a character concept that has a [i]reason[/i] to still exist [i]within[/i] the narrative. My two cents again.
