We remember when video games were little more than pixelated characters bouncing about the screen. That was a simpler time: no one really talked about the power of a particular physics engine, or whether or not a game was ‘realistic’ enough, because it didn’t really occur to most of us to ask. It wasn’t something we considered a vital element of our gaming experience. Games were fun distractions, simple escapes from reality. They weren’t, in most cases, all that realistic, though some were quite complex and in-depth.
