Thanks OrangeBrat for that information.

I had a look at the game list made with WME, impressive:

I know a person who was part of making graphics for the game "Sunrise". This was a professional project made with WME and professional speakers. It got even good ratings:

WME is more than battle-proven now for adventure projects.
