So while they're off spouting more diamonds™ get 'em in piss yellow and poop brown! It's love! commercials, I've got ya covered.
Fallout 4 Valentines! Feel free to swipe, share, send, whatever it is the cool kids do. Or horde them all in your dragon lair. I've got one for every companion (which that was a god damn lot there, Bethesda) and one surprise valentine. Ready that scrolling finger, we're gonna be here awhile.
Nick Valentine (It got a bit Inceptiony on my computer for awhile with this one)
And last but not least...
Go, share, and revel in the awkward flirt a couple times then call it a romance. Or, if slightly more complicated is your style I still have all my Dragon Age valentines from Origins, 2, and Inquisition.
Or there are the Mass Effect ones.
All the nerd love.
