You know what more games need to have? A hug button.
This inspiring innovation is introduced in the gameplay demonstration for A Boy and His Blob seen above. Okay, so maybe an "embrace command" wouldn't pan out too well in, oh, say, Gears of War. Perhaps hugs are rarely appropriate in a video game context, requiring the presence of anthropomorphic gobs of slime to be considered acceptable. We don't really care about all that stuff -- all we know is that our hearts have been warmed to a point where eggs could be scrambled on our bare chests.
