just curious don't games in english work or are those divided by region as well? --- The only Vita games really worth getting: Gravity Rush & P4G Being unable to detect sarcasm and lies might be an early way to catch dementia
language and region are very different things. a 3DS from the UK won't play any US 3DS games, even though they both use English. a UK 3DS does play French, Italian, Spanish, Dutch, etc. games because it falls under the European games. the regions a game can be locked to are Asia, Europe(Australia falls under this region), and America(all of it including south America and Canada).
only DS games made with the nitro dev-kit(ntr in the part/game code) are guaranteed to be region free, and 1 or 2 of the games made with the twilight dev-kit(twl in the part/game code) are also region free. the majority of the twl games, and all 3DS games are locked to the region they where made for.
