I started getting into visual novels a few years back when I wanted to read the source material to all of Key's anime adaptations. Once I managed to read everything by Key (excluding Air, I don't think there was a completed translation at the time), I was looking into new VNs to read through. I saw all the praise Muv Luv was given from /r/visualnovels as well as it's rank in the VNDB, and decided to give it a go.
I told myself when I first saw the Prefundia I would only back the $50 for the entire trilogy. I was a little annoyed at the price hike to $60 since I'm kinda broke, but whatevs, it's Muv Luv. However, I ended up backing $100 so I could get the Photons and the Codex. The more I think about it, the more I want to upgrade to the $150 since it's such a good deal. My poor wallet...
