Tried Jackal Assault, Trackmania VR and Kismet today.
Kismet was ... alright, but it doesnt offer much, even considering the boardgame they packed in. I liked the visuals in that area, but its the first VR game I have deleted after going through it, as I dont think its particularly worth showing off to others.
Jackal Assault was interestingly enough a lot more engaging than EVE was. Might just be me, but I liked the controls quite a bit better, especially the head targetting for missiles, while you were free to shoot ahead. Unfortunately its only short, but will keep this as space flight showcase instead of the EVE demo.
I already owned Trackmania, so a free VR update is pretty neat in my book. This game made me a bit queasy with some of the looping levels, but it has a tremendous sense of immersion. Quite a few of the levels have you going up/down ramps or making huge jumps and it really works incredibly well. There are only 40 shorter VR levels, but its definitely recommended to grab. Replaying for the highest (green) medals will give you plenty of challenge/replayability too.
