Inception
Inception is another one of those films who’s premise is genuinely perfect for a video game. Having people enter others dreams to extract info is a brilliant idea and it could work with any number of games because of how much breathing room that offers. Having Assassin’s entering the minds of Templars or others could offer unique gameplay experiences we have yet to see in this series, thanks to the sheer limitless creativity the levels could have. It could also make combat interesting since shifts in gravity and such would come into play when fighting enemies.
Groups like Abstergo could easily go from prodding at memories to searching through the dreams of others when trying to locate mystical artifacts. From a story perspective, this could make the future events far more personal than they ever have been, as the concept of entering someone’s current thoughts is probably about as close as you ever want to get. We could also be haunted by our own subconscious, which is a nice way of laying out exposition about a character’s past without it being so overbearing.
