First of all I do not think that downloading games from PS3store or whatever does effect any prices of sealed games.

Like gemini said...there are a lot of people out there who want something physical in their hands.
Furthermore: Why should it infect the sealed collecting??? Sealed collectors want the first release....not a game for download or a 7th release on the Nintendo DS.

It can be, that the prices are going down at the moment....but who cares??
I collect sealed games since some years and I know times where you got (for example) a sealed Mario RPG for 150 Dollar...for some month it was going for 700+....and now for 450 Dollar. And I could bet....when this game isn't in ebay for 3-4 month...the next one will get 700 Dollar again.

The actual problem is that some so called "collectors" who have 2-3 sealed games for reseller reason see those prices and throwing their games on the market to get a nice gain.
If those games are in REAL collectors hands...prices also will go up again.

When you look at the collecting (and pricing) scene 5-10 years ago...you can see a lot of differences.

I wonder if there also were some noobs 70 years ago who said to a collector of Marvel comics:
Are you stupid??? Why are you collecting this shit...it is worth a Penny.
And now??? 320 000 Dollar for the first Superman comic....huuuuuh.
It is all about conditions....
And yes...you can compare comics and videogames.

But sealed collectors should not collect because of the money...that is stupid. Collecting should be fun...no matter if the games are used or sealed.

@sonicwolf
nice catch your sealed 3DO games...
You can't understand why people keep some games sealed and never play them??
If I wanna play a game...I will buy it for 2 Dollar and play it It is that easy.
And I can also have it sealed.
