You'll get used to this system, particularly if you haven't played the PS2 version, but we didn't find it quite as natural as some reviewers have suggested.
Other motion controls include flicking the remote to launch attacks and tilting the nunchuk to dodge during fights.
Even after a long period of acclimatisation we still couldn't make some of the nunchuk motions register correctly every time.
On the positive side, however, the enhanced speed of the basic slash attack with the brush means you can be a lot more aggressive in combat, and fights tend to be over rather quickly, leaving you more time to explore.
The world of Nippon is divided into several large hub areas, with villages and sub-levels scattered all around.
You can enter every building, talk to the residents and sometimes receive bonus quests such as catching fish or locating troublesome monsters.
It's so easy to become sidetracked that you can spend hours in one main area, just collecting things, feeding animals, trading goods, earning money and searching for treasure.
By the time you remember to move onto the main quest, that's when a whole new area unfolds before you, followed by another, and another, and another... The scale of the game can be quite intimidating.
Fortunately you can warp between the main save points - just as well, because running from one end of the country to the other takes ages, even at wolf speed.
The other technical issue is related to the look of the game. If you want to compare the Wii version with the original, the graphics are much sharper and brighter on the newer console.
On the other hand, the PS2 game has a lovely parchment effect, which shows through the graphics and adds to the hand-drawn look.
Both versions seem to run at the same framerate, and there's the same amount of pop-up - so not a great deal of difference, really.
During our long, somewhat awestruck play through Okami, we must have run into at least three or four parts where we thought the final scene was moments away.
But each was just the prelude for something even grander, and because the ultimate goal doesn't become apparent until very late in the game, most of it comes as a complete surprise.
Make sure you don't miss Okami this time.
