Gah, Ninja'd again! But yeah, import them if you can. You may have a problem region-wise with the Wii one, so do a little research before investing, but the DS is region-free, so at least that one's not a problem.
As for the original topic...
Adventures in the Galaxy of Fantabulous Wonderment. It's by Yahtzee, but is inevitably overshadowed by his immensely better known Chzo Mythos series. It's also a slightly odd mix of classic adventure gaming, platforming and space sim. But it has adventure game sections, so I'm counting it. Also, it's brilliant. Go give it a try.
On a similar subject, give his
other games a try. Anything above the Rob Blanc trilogy in that list is generally pretty awesome, though the bottom two games aren't particularly amazing. But then, most people's first games aren't, really.
