As much as I hate to admit it, the live shows have become rather creatively bankrupt... they're re-staging 'new' versions of the same plays from previous games, and the quality of the music has been on a steady decline.
And there hasn't been a new ST game since V came 2 years ago, other than endless ports of the original games onto new platforms. At least they were trying to put out new, original side story games to fill the gaps between major releases. I'd much rather get a new Hanagumi Columns game than yet another port of ST1 or 2. Every time Microsoft releases a new version of Windows you can bet Sega will go back and milk the dried cow once more.
