Is there a version 3 now? There were none in the UK/Europe for a while and now there seems to be new stock, they have some differences such as no hot glue on the boards. Some of the games have sound issues that were not there before... World Heroes 2 has the music all mixed up for example. I could be wrong so don't quote me on any of this.
Captain Kids stage plays Erik's ending theme. Afaik, version 1 has no hotglue on the boards, version 2 has it and the newest stock has no hot glue again. Weather they can be regarded as "Version 3" I dont know...
