/vr/ - Retro Games

It's not quite retro, but worth mentioning. For anyone who really likes Ghost Babel, I highly recommend checking out the Boktai games. In many ways they feel like the spiritual successor to that game, incorporating very similar stealth elements.

They're both very fun and engaging action RPGs with some interesting gameplay elements. The one thing to keep in mind is that although I'm sure they can be emulated, playing them properly where you need to use the sun to your advantage adds an extra something to the whole experience. At least it did for me.
