Summary: You get 2 excellent cave shooters for that price, it's a steal. Both games are very well crafted. The art design and music are beautiful. Also the pure scoring mechanics guarantee virtually endless replay value. But be warned though. Pink Sweets is the hardest cave game I've ever played (even harder than Guwange!). So 1cc is a really steep challenge. Don't worry, you can credit feed through bot games and still have a lot of fun. You can collect easy achievements too btw.
Summary: Cool game to play. I wish there was an online Co-op, more playable characters in Muchi Muchi Pork in, a limited edition of this game, the DLC where included in this game where the bosses from Pink Sweets appear in Muchi Muchi Pork! & a Muchi Muchi Pork! & Pink Sweets arcade stick was released with this game.
Summary: Two of the best shmups I've played on the 360 yet, and the $40 price tag is great compared to most other CAVE titles. The arrange modes are insane, and the scoring systems are creative and lots of fun. The different modes are drastically different, so it's practically four games in one. I'm going to be spending a lot of time with them.
