but it's obviously just to milk money from all the die-hard fans.
Or maybe the die-hard fans just really enjoy this sort of thing and they want to buy it. Ever think about that?
If I am a fan of a game series (as I listed on Page 2), I will pay the cost for any Collector's/Limited/Legendary Edition of a game. I love the extra swag, that's why I buy it, and also because I'm a collector of such things.
In no way do I feel cheated or swindled. If you feel that that is the only reason it exists, then just don't buy it. By the Gods it's not that big of a deal, but please don't belittle the people who do enjoy these things just because you don't see the point in it.
Doing so only makes you seem ignorant and elitist, and nobody wants to look like that.
