After seeing on Loke's blog that Guitar Hero 3 would run on Windows Mobile, I had to check it out - especially for $15 (15 songs). There's a subscription version for getting additional songs on a monthly basis. Anyway, it works pretty well on my BlackJack II.
Let me know if you want to see a demo. Me, showing a customer Guitar Hero on my Windows Mobile phone - now that's evangelism!
Thanks to Magmic Games. Get the details here.
