What's the value of?...

[SwiftDeath]

1) sealed steelbook of Saints Row;

At least 75 euro in my opinon, maybe get it cheaper off of ebay.fr if seller doesn't know what he has

2) sealed steelbook of Saints Row 2 (PS3/Xbox360)

I would say that a sealed Saints Row 2 G2 steelbook would easily hit 250 euro maybe 300 euro

Sealed G1 xbox is probably closer to 100 -125 euro

3) used steelbook of Saints Row 2 (PS3/Xbox360)

G2 mint without sleeve is at least 120 euro but probably more like 150 euro
With sleeve probably 175 euro

Auction above doesn't accept paypal, doesn't ship out of germany and still goes that high

G1 without sleeve I wouldn't pay more than 15 euro for because you can find the PC edition rather cheaply if you're patient
With xbox sleeve probably 40 - 50 euro

Just my opinion of course

Has been a while since I've seen a sealed saints row 2 sell
