Ikaruga?

Ikaruga is awesome. You can play for survival, chaining or just messing around.

I have a sealed Dreamcast Ikaruga. I've been meaning to buy the Gamecube version but according to the folks at ikaruga.co.uk, the PAL Gamecube version has bugs which affect your score with the first boss. So I've been waiting to see an american one pop up somewhere, but no such luck.

Ikaruga is definitely one of the best shooting games I've ever played. It sits by my favorites, Raiden DX, Mushihimesama and ESP Galuda. I highly recommend it, but don't expect to complete it without credit feeding. The goal of Ikaruga is to complete it without losing a single credit, arcade style.

I also recommend Shikigami no Shiro II, if you're looking for an alternative shooter for the Gamecube. It's a combination of CAVE and touhou shooters all mixed together.

Jam it back in, in the dark.
