Yes, I'd say a Wii is worth it. It's not the investment a Playstation 3 or XBox 360 is, and the Virtual Console alone is a great way to add more games to your library without spending $50 a game. (How does $8-15 per game sound?) Plus, I have a ton of games that I'd always be willing to part with if you wanted to try more games. Last but not least, if you or anyone has, had, or plans on getting any Gamecube games (and a controller/memory card), the Wii is backward-compatible. I love being able to play my Gamecube games that way since it means one less system I have to hook up just to play something.

(I still miss the little boar Pokemon I dreamed about. One of the starters in the next game is a fire pig type, so I'm curious to see what that's all about. Make it adorable, Game Freak!)

Edit: Checked your local game store for used Wiis. Sometimes you can get one in great condition for cheap, and even better, games purchased through the Virtual Console are console-bound, not account. A friend bought a used Wii and found she had access to a lot of great classic games thanks to the original owner. ^_-
