I spent $80 on a double-pack of Cave’s Muchi Muchi Pork and Pink Sweets when I visited Tokyo last fall. Some people might think I’m crazy for paying that much on what could easily be a $5 downloadable game. But if you’ve been bitten by the shmup bug then you know who CAVE is and why such a purchase isn’t only acceptable but absolutely necessary as a fan
Siliconera knows Cave is bringing Dodonpachi Saidaioujou for Xbox 360, but what else is the maniac shooter company working on? They picked the brain of Cave lead creator and Game Development Head Makoto Asada to see what their future plans are.
Cave has a mega collection of shooting games according to Amazon Japan, which is taking reservations for the Cave Shooting Collection. This bundle includes 10 games plus downloadable content on seven DVDs.
As a port of an arcade game, Akai Katana may be short but it is still incredibly fun and provides a seemingly "impossible to beat" kind of challenge that is lacking from a lot of video games today.
I don't understand releasing a niche japanese title like this for the 360 which has almost no audience for it.
