I consider myself also old in this regard, having really enjoyed games like Galaga and Mario Brothers on the NES and with Tiberian Sun as one of my most favorite games of all time.

I'd say the most recent time I've been blown away was using Vive's full room VR setup. Many VR games have some very primitive concepts and graphics but it's a very different way of gaming even in multiplayer. There's a lot of room for improvement in graphics, but even _more_ room for improvement of controller hardware designs.
