THE PCG Q&A

Find all previous editions of the PCG Q&A here. Some highlights:
- What's the best summon you ever summoned?
- What should boomer shooters be called?
- Have you learned a real-world skill from a game?

It's something you probably don't think too much about, how you go from crowbar to 9mm pistol to GEP Gun to The Blade of Kings in an FPS, but on a casual survey I was surprised at just how many mouse wheel switchers we've got on the PC Gamer Staff—it just seems so fiddly and clunky to me! I'm a ride or die number row arsenal manager, with the Q key in reserve as my go-to "switch to last weapon."
