This is an opinion thread, I think I'll point out first.
Something I am wondering, regarding how Only War will go; what might take the place of some of the cool stuff various characters often aspire to acquire? If you are an Inquisitor, you have cart blanche access to most of the coolest stuff in the galaxy, and your direct underlings can probably get some of those via being under your umbrella. No one except another Inquisitor is likely to call you on it, either. Rogue Traders have a similar access, either by virtue of having more money than most Sub-Sectors, or by stealing it from some hole they just dug threw. Their Warrant gives them a certain amount of immunity to persecution, and their penchant for being outside the Imperium's borders helps with this immensely. Space Marines are some of this stuff, and while they rarely go looting for alien gear, or ancient toys, they do possess a number of both, and CAN requisition such things, if the need is really there.
Then we get the Guard; the group the universe doesn't care about. They have no names, they live and die in droves. While I wholeheartedly expect them to break with the regular mold, and tweak in things to make individual Guardsmen important, and thus fun, worthwhile characters, what are they maybe to do to fill this particular gap that the game might have? Much of a game is the acquisition of better stuff, preferably rare stuff, but the Guard doesn't get such stuff. If they find it, they give it up, or pay a high price when they are found out. They don't usually req awesome stuff; that's not necessarily their place. They are likely to start the game with lasguns, and maybe aspire to plasma weapons, meltas, and heavy bolters, someday (and these might only be certain specialties; an Officer might get a Plasma Pistol, Power Sword, and/or Refractor Field, but not virtually anyone else, nor is anyone other than the hw wielder likely to get the heavy bolter, rocket launcher, or what have you, and only Stormtroopers or Vets are likely to get carapace, and hot-shot (better) las-weapons). Finding an archeotech plasma pistol, when you don't use them, or can't keep them, is sort of a let down, while finding an Eldar Firepike is akin to finding a Chaos Altar; it's evil, and you don't even want it/can't have it, even if it might be the best weapon your group has yet encountered. So many "important" Guardsmen have spent their careers making due with just the lasgun, flak armor (carapace if they are fortunate), and hope in the Emperor's blessings. What might the book fill in the "Ancient Relics, Archaeotech Wonders, and Artifacts of Xenos" Chapter/motif with? What might Guard characters, still being Player Characters, who want to feel important among the multitudes of faceless ready-to-dies hope to get to feel like they are getting better?
Okay, opinions please?
