CastleStorm VR is a relatively enjoyable game with an addictive loop, and it's easy to lose hours to it. While I wish more was done on the VR side, it's a solid addition to the game. It doesn't do much to improve the lackluster story or repetitive gameplay, however. Addictive or not, some variety would not hurt at all.
The Solus Project does what it sets out to do — immerse you in a dangerous environment for a dozen or so hours and task you with surviving long enough to experience the story. While I wish there was a bit more to the plot, and while the controls frustrated me, it's a fairly solid exploration and survival game. The VR component makes it worth investing some time in.
