No you dont need gold,gold is for MP only.

Yes, but... in Europe, we don't have Rock Band 2 with instruments as in the US. I can only get RB1 intruments, which are far worse than Guitar Heroes' ones.

As an owner of both the 360 and Wii, I'd definitely go with the 360 version. DLC is less of a hassle because of the Hard Drive, if you plug the systems into an HDTV you'll actually get some benefit from the higher resolution display (it makes it easier on the eyes to track all the instruments and lyrics), and in the event you get a full surround sound setup hooked up you'll get better audio fidelity out of the 360 version than the Wii version.

I actually held out on purchasing any Guitar Hero / Rock Band games when I was a Wii only owner (I bought a Wii on the morning of the North American Nov '06 launch and didn't get a 360 until May '08). While the games are certainly still a blast on the Wii, if you have a Wii and either a PS3 or 360, I'd say (without reservation) to go with the HD console version.

The only downside is, of course, that you don't have free online play on the 360.

And that's a very big downside to me.

I went to the Wii version. If the DLC works as they say (with SD), there won't be a problem. The online system on the Wii seems "perfect", being always online such as with the X360 version (I think it's the only game that does it). I already got 3 Wiimotes, with the price defference between both versions, I'll purchase another one.

This said, to me, the HD definitely does not compensate the online (and yes, I own a 42 inch HDTV). About the fidelity, I own an Onkio and I didn't notice the difference you say in other games. I hope this is the case as well.

Nevertheless, thanks a lot for the information and opinion :)

Well, hey. As long as you're happy with your decision! :)

Have fun with your new game. For all of us it's simply a matter of weighing the pros and cons of our options. I'm glad to have been some help.
