A lot of it might just be his taste in games just does not translate to the larger American markets. SingStar and Buzz? 99% of gamers here don't even know what that is.
Isn't this SCEA's ineptness? Singstar is so ubiquitous in Europe and music games hit such a nerve in the US that I can only imagine that Singstar's failure to catch on was SCEA's own damned fault.
