If You Own a Wii, You Should Own Okami
Let's get serious here, people. For $39.99 you can get one of the best, most under-appreciated games for the PS2 with the addition of 480P and native widescreen support! Not only that, the game translates so well to the Wii controls that you'd think it was built for them. Even better, you can skip the longer cut scenes now, one of my few complaints about the original. It's a great price, a landmark title and I'm enjoying myself just as much now as I was in my original play through.
Okami doesn't have a cynical bone in the whole body of its design. It's just a joy to explore and experience. If you're into Zelda-style adventure games, don't miss out.
