"Look at most of the games you see -- they're defined by who you kill or what you destroy, which is a limitation in itself," he said. Cage laments what he considers a stagnation in most games over the last 25 years, which are based on violent interaction, and the same gameplay tropes.
Quite a bit of good stuff in there. Would have been interesting to see the entire speech.
