So, what games do you like that are almost completely obscure to the general public? Just to start:
Touhou series. While I was browsing around 4chan's /f/ board, I came across this flash. My curiosity was somewhat peaked at that moment, having no idea of what it was about. I started searching around for Perfect Cherry Blossom, and once I found the demo for it, I was hooked. Coincedentally enough, it was enough to get me to like bullet hell.
Cave story. I only saw one of my friends play this in one of my classes on occasion. When I started playing it, I took a liking to it's story line, and the NES style graphics and sound.
Bunny Must Die. I don't have much of any real idea of what is going on in this game, apart from a flat chested bunny girl doing shit. It's fun, and it reminds me of Castlevania. It is a simple game, since you run around collectig power-ups, and fighting bosses. To add more insult to injuy, the ablity to move right is a power up.
