I’m taking this topic to be less of “what’s the most important video game” (which we already had a long discussion post about recently re: the BAFTA award thing) and more of “what’s the best game to just sit down and play right now”. In which case, probably Portal 2? I can’t think of a much better candidate in terms of being a perfect execution of what it sets out to do with an appeal that can be compelling for absolutely everyone regardless of taste.
