One of my biggest regrets was opening a factory sealed pal UKV copy of fire emblem radiant dawn wii.
I was a beginning collector and radiant dawn was so hard to get at that time new. Stores were not selling it until one day some guy sold em for 45 euro's shipped original factory sealed red nintendo strip brand new and english versions as a added bonus copies.
Not only is the british english version the most desirable and expensive one to get in europe but also really hard to get in my country with only dutch copies for such games.
I did enjoy the game at that time but as the fire emblem fan that am I will likely never come across a factory sealed copy for 45
I wish I would have just left it unopened and gotten myself a used dutch copy for 20 30 while keeping the UK one sealed
Even used dutch copies used are 70 these days.
