U.N. SQUADRON
Not one of the anime girl shmups, but still a fucking radical ass game.
I picked up Ikaruga at a Gamestop a few months ago for Gamecube. I'd been emulating the Dreamcast version for awhile, but it had some emulation hiccups. I nearly had a heart attack when I actually saw it in the store (THERE WERE EVEN TWO COPIES!)
