We just got a Wii 2 weeks ago, and my husband and I are both currently obsessed with Paper Mario. Go! Buy it! Now! The Wii controller is held sideways, which seems superbly weird, but it works really well. It has great classic platformer elements, but has a little RPG base to it that makes you want to keep coming back to it. Lots and lots of fun, and surprisingly challenging.
We also have Wario Ware which I really, really like. It shows off the Wii controller really well, and if you have a short attention span, man is that the game for you. The only weird thing is that I went in expecting it to be multi-player, but you don’t get the privilege of playing multi-player until you’ve beaten the game in single-player mode one. However, if you want to have friends over and show them the Wii really quickly, it’s the way to go.
Also, even though it’s $5, I really am glad we got the Internet channel. It seemed like a total rip off at first (I mean, they were giving it away and just started charging for it a month ago!), but it works much better than I expected. It’s based off of Opera, and renders most webpages just fine. As a matter of fact, I was surfing the Dope on it yesterday.
