Will 128gb SSD MacBook Pro (retina) be enough?

I plan on buying a 13" MacBook Pro with retina display really soon. I thought it has the 500gb hard driver like the regular MBP, but it only has 128gb of SSD. I planned on using my MBP for web, light email, some HD video editing, storing pictures and videos, and light gaming like Minecraft. Would I be fine or should I got for the 256gb for an extra 200? :/ I really don't wanna spend the extra money, but if it's worth it I'll do it.

I don't think youll need the 256gb option, but if you need extra storage a 64gb usb is like £30
