In the early days of virtual reality games, experiences can largely be divided into two categories: those built explicitly for VR, and those that tack on VR like a promotional bullet point. The latter is a great way to get people interested in the medium — hey, it’s Final Fantasy in VR! — but because of a lack of investment, both in time and forethought, these experiences range from forgettable to terrible. When VR is an afterthought, you can tell. Unfortunately that’s the case with "Blood Ties," the latest downloadable add-on for Rise of the Tomb Raider.
