No, they sell for €30... Metroid prime 3 sells for a pathetic 10 euros here in every store.
Metroid is a core game, and only hardcore fans will buy the game. I think this has been proven 3 times already if you look at the sales. Those remakes won't get great sales, atleast not over 2 million.
I'd still rather pay €30 then €50... If I would be able to sell my metroid prime 3 copy, then I would buy this trilogy, but no one wants that game.
