Well, we recently started playing the Campaign Setting by Reality Blurs, which is a "Perfect Cocktail between horror and Espionage", and tough we're liking it, there's not a guideline to limit equipment other than "The GM says so", which doesn't helps, as my players always ask me a "WHY?!" and then we begin playing Q20 instead of roleplay.
Well the weapons options presented are quite nonsensical, as there's ALWAYS something better, for the same cost. Why would you pick a Slug Type Shotgun with 2d10 damage over a Shotgun that does 3d8 damage, both costing the same? Plus ranges in Savage Worlds are BIG, a ranger RARELY is fighting mid-range, let alone long range, so a Pump Action Spread Shotgun is gonna be doing 3d8 damage almost always, specialy since Agents of Oblivion lets them pick a free edge each mission, and if they pick Gun Fu they'll be shooting adjacent enemies with a shotgun.
Since there are not stablished, written limits to the weapons they can take, how can I give them a big NO when speaking about weapons? they're just novice rank, they'll argue if I say it's because of the rank since it's no where on the guide.
