"#2 Big Brain Acadamy for DS (called 'Dr. Kawashima's Brain Training' in germany)" I believe number 2 IS (Dr. Kawashima's) Brain Training. Big Brain Academy is whole different game (i do have them both). Brain Training do have a different name in NA, but now i cant remember what is was (but it's definately not BBA).
