The company bringing a performance upgrade more than a decade after launch feels like a fitting close to Unity's development. The game suffered from bugs and performance issues from the jump, and while most of those did get addressed, no amount of big fixes or free DLC could fix this howler of a story or make Arno any more compelling as a protagonist. But every fan has their own passionately argued take on which titles are the worst, so just because I found Unity to be a particularly low point in the series doesn't mean it's not going to be a fave for somebody else. So if you are someone who, as Ubisoft put it, has been waiting a long time for a chance to dive into Unity on modern hardware, then tomorrow is your lucky day. Amuse-toi bien.
