I honestly think $30 is a little steep for Defense Grid 2 VR, and in time, competition will likely drive that price down by $10-$15. But with that being said, I don’t think any tower defense fans would be disappointed if they paid full price for it.
All-in-all, though, as much as I enjoyed my time playing, if you’re limited on funds, the $30 is probably spent much better on other games that I covered during the stream. This is far from the best value, and I’d only recommend it if you really enjoy tower defense or have a bunch of spare funds to blow on games you’ll play a handful of times ;)
