When I was a kid, light guns were pretty much the pinnacle of gaming and toys combined because you could see if you hit something rather than pretend. Any time I went into an arcade I went straight for the gun cabinets, plus I paid way more money than I was willing to tell anyone at the time for the G-con Resident Evil Survivor bundle. That game was terrible too, but the chance to actually aim and shoot things in first person still blew me away.
Anyway, here's zadoc's trip down light gun memory lane. Hopefully we'll see more of his stuff soon.
