Question about Sony Playstation VR v2 + Camera + VR Worlds

Somewhat naive question... where is the difference between this product and this one: https://www.galaxus.ch/de/s1/product/sony-playstation-vr-mega-pack-2-camera-5-spiele-vr-brille-12043970? Apart from the word "mega" and the price, I can't find any difference 🧐
