My friend bought the Only War Beta and we ran a session with it and I must say I am impressed with the system. However, during the game I was reminded of an idea I had way back for Deathwatch. That idea was full weapon customization. Now at the time we agreed space marines were highly unlikely to just begin swapping out parts for their bolters, but for guardsman I could see this happening.
When I say full weapon customization I mean breaking the weapon down completely and offering upgrades for every slot. This would mean full customization on scopes, barrels, gas system/charge type, grips/under-barrel weapons, side rail upgrades such as heartbeat sensors, aiming lasers, and lenses, different stock types, trigger controls, magazines, grips, and pretty much any other part that could be thought up. Upgrades wouldn't really be anything drastic, perhaps a different barrel type might increase damage by +1, and a grip provided a minor +2 to BS, but I like the idea of full customization to be there. So does this seem like something a guardsman would do? Would it even be possible for them to acquire all these aftermarket parts? In general, does the community see this as a valid idea? Thanks in advance.
