GCN
Giftpia (JPN)

I don't know any Japanese, but only one game gave me trouble: Giftpia.

Osu! Tatakae! Ouendan 2. It's Japanese Elite Beat Agents.

What's the point of playing Mother 3 if you don't know Japanese? The main attraction of the game is the story...

I don't get why people import games if you can't read it. If the game has no story like Geometry Wars that would be okay with me though.

The only game I imported from another country directly was Trauma Centre: Under The Knife 2 (US).

I also had an import copy of NFS: Carbon (Australia, got rid of it), Universe At War: Earth Assault (PC, US) and Diddy Kong Racing (US) but they were all bought in the UK or bought online from UK based sellers.

I have Megaman ZX but not Advent. Is it any good? I might import it too.

I import most my ds games from america due to prices. I am not gonna list em all though.
I have however Imported some thought to be Japan exclusive like Tatsunoko VS Capcom and Rhythm Tengoku Gold

Dreamcast Broadband adapter(Asia)
Castlevania: Dawn of Sorrow(UK)
Castlevania: Portrait of Ruin(UK)
Final Fantasy Tactics (USA)
Final Fantasy Anthology (USA)
Parasite Eve (USA)
Resident Evil 3 (USA)

Saturn: Silhouette Mirage
PSP: Parodius Portable.
That's my list...not very big...

Advent is better than regular ZX IMO so definitely worth it if you liked ZX.

Dreamcast: Fighting Vipers 2, Virtua Cop 2, Giant Gram: Japan Pro Wrestling 2, Zero Gunner 2 (yeah alot of 2's lol), Guilty Gear X, Sega Tetris, Puyo Puyo 4

Saturn: Japan Pro Wrestling Feat. Virtua, Parodius Deluxe Pack, Dead Or Alive, Puzzle And Action Sand-R

DS: Daigasso Band Bros., Tingle Balloon Fight, Game & Watch Collection 1+2

All of these are Japanese.

If this even counts, Bomberman '94 on the Virtual Console for the TurboGrafx-16. That's it.

If we're including VC imports from the Hanabi Festival's, then count SMB: Lost Levels, Sin and Punishment and Super Mario RPG for me

I don't think we should count them unless you've region hacked your Wii to use another store.

I agree. That's why the only physical game I've imported from Japan was Tingle's Balloon Fight DS.

I imported Tingle's Rosy Rupeeland from the UK, and if I ever get any money, there's a couple of DS Bomberman games I would like to import as well (darn Hudson for never releasing those over here anymore!).

On VC, I have Do Re Mi Fantasy (because Corbie paid for it; otherwise, the lack of translation would've kept me away forever) and Pulseman. So not too much, really. I would LIKE to have Mario Super Picross and Devil World, if Nintendo would ever freaking RELEASE THEM HERE!
