Despite the name, what the National Video Game Arcade (NVA) in Nottingham showcases are not "video games" in the exclusionary, borderline threatening sense, but the broader idea of "play." There are arcade cabinets, modern and retro consoles, and idiosyncratic exhibits from broader gaming culture. Designed like an art gallery, it's a tribute to how the fundamental experiences of games, the pleasures of challenge, interaction and sharing, are universal.
The same can be said for Gamescom, an annual trade show which kicks off in Germany next week. It's a trade show, so a lot of pre-launch, pro-industry hype gas gets blown around, but Gamescom is open to everybody - kids get in for free and as much as unreleased games, the floor space is dedicated to curious and unconventional exhibits.
