I see where you are coming from. But the second copy is honestly for trade towards a game I have yet to add.
As for the need to open and play a game which is interactive and unlike films passive I get as well. But this is not a rare game. It is easy enough to find open to play. In that regard I think a few unopened copies how ever may exist can continue their sealed lives as parts of a collectors well collection. They if anything are representations of the games fresh.
If whome ever receives a sealed game new or old desires to leave it sealed that is their choice as at some point the game will pass hands and someone will open it....even if it is just time that unbinds it creating a unsealed game that if anything if very ready to be played with....a per verbal virgin game...
Now if I were to go and blah grade these sealed games thus removing the choice of anyone ever opening and playing them that I think would be a step to far removed from what gaming is. The simple act of enjoying the game. Be it to beat it compelte it or master it with the next high score has always been my attraction to gaming since I first owned an Atari and would play with my father........
Firstly, arrrright...
Secondly.... just open one of your two sealed copies...if you actually intend to play the damn thing, don't buy another, that's pretty... yeah....
Thirrrdly, having a sealed copy for trade bait, I guess can be a thing... I guess. blah.
Fourrrthly, The is/isn't rare factor shouldn't really be a thing. The fact is that you said you were going to maybe purchase an open copy of a game that you have twice, sealed, instead of simply opening one. Eff.
FIVE5 mai daddy gawt me into gaming on an atari 5200 which had been out for a thousand years by the point I was playing it. Haunted by Empire Strikes Back and ET to this day. Effffff. Thankfully an NES was purchased shortly after, but then again my big bro was a butthole NES hog. So... yeah.
