Stahlfeder: Tekkou Hikuudan

I'm really not sure why this game garners the hate it does (when it gets any acknowledgement, anyway). I know it's far from the peak of the genre and it's certainly not without things that would dissatisfy diehard STG players, but when you boil it down, it's… really not doing anything particularly wrong or different from what you'd typically expect. It's slower than the likes of, say, Ikaruga, and much easier than it too, but I think it's really nice to have something that's both an entry point and something you can just suck down in 30 minutes and have a good time, even if said time isn't an exceptional one.
