I'm pretty sure both versions come with achievements, it says in one of the other threads.
If you get the dlc though remember to get the same Country specific points as the overseas account you create to download it.
So Japanese 1400 points for Japanese account, Asia points for Hong Kong account etc.
Other region free games, hmm
Mushihimesama Futari Ver 1.5
Also just released Muchi Muchi Pork! & Pink Sweets
Note though, these are not at all easy 1000's like Virtual-On, on the contrary extremely difficult.
