This game was developed as a VR game and it will function and play a lot better than non-VR for sure. In non-VR, you feel more like a spectator and occasionally chuck in some basic strategy gameplay. Honestly, I have played a lot of Warhammer games by this point and this is one that is really basic from the commands to the build-up and level design. I would have a better time of it in VR but outside of the headset is not as fun or in no way near as engaging as other titles in the genre. You have very basic settings and no way to rebind or even bring up the controls for the keyboard. In VR it’s all straightforward but outside it honestly feels like they ticked the box “no VR” and just walked away. The game is not available anymore and you are not missing out.

Gaming since the Atari 2600, I enjoy the weirdness in games counting Densha De Go and RC De Go as my favourite titles of all time. I prefer gaming of old where buying games from a shop was a thing, Being social in person was a thing. Join me as I attempt to adapt to this new digital age!
