The place is bigger than I originally thought and has probably at least 10-12 VR stations. I came with my friends, and we used the groupon for 30 mins of gaming for 4 people (it came up to like $7/person). The staff were very helpful and answered all of our questions before we started, and helped us choose a game. The only annoying thing was that they don't have a catalogue of games for you to look at; you just have to rely on the staff to choose. The clock didn't start until all of us were in the game, but the sound in my headphones didn't work properly and when I took my goggles off to ask for new headphones the staff member was gone and I didn't want to waste time going to find them (we were in the back room).
We played this basic FPS that involved shooting waves of robots. The novelty of the VR was fun, and playing with your friends and seeing them around you in the virtual space was cool. I definitely wouldn't play this game again, though, because it had no progression and nothing to do except keep shooting the aliens that spawn. You could choose between being a human character with guns, or an alien with a sword. I chose the sword, which was a big mistake because you have to be right next to the robots to kill them, and my friends with guns kept killing the robots I had been moving in to kill.
In conclusion, if you've never played VR games before, I would check this place out because the novelty of the VR is what makes it fun. Make sure to use the groupon, which seems to be perpetually available (it's been months and it's still there). I'm going to come again and try a different game and see if it's any better than the first one.
