All this is from vgchartz, so if you want more details on other stuff, head there.

So, I'm sure some of you have been wondering how some of the recent software has been selling. In my opinion, the past month has had more quality game releases than there were for - basically - it's entire first year. And now the numbers (first week; second week):

Guitar Hero III - 271,053; 98,121 (~370k)

Manhunt 2 - 51,371; 23,168 (~75k)

Mario & Sonic - 81,445

Fire Emblem - 66,711

Lego Star Wars - 37,119

If anyone is curious, GHIII for the 360 broke the 1 million sold mark.

wow Guitar Hero III

nvr knew it's really that populr.... hmm should i try it out?

I like it.

Trying to get a second guitar for it actually.

No surprises there for me
Maybe redoctane/neversoft can use some of that profit to fix the mono sound in gh3

mario galaxy will be on the top soon enough, but ya, good for guitar hero 3 for wii, its selling more then i expected it to sell

Thanks for the info. I don't think the price is worth it for Guitar Hero, I bought the first one, but I doubt I'll ever buy another one. They're overpriced, but very entertaining, if I need a GH fix I'll head over to Best Buy and play their demo.
