Any special reason Dead Space costs 20 dollars on but costs 10 dollars on [url=http://store.steampowered.com/app/17470/?snr=1_5_9__300]steam?

It's kind of a ripoff for GOG to be 100% more expensive than steam, shouldn't the price be the same?

the price politics here are weird.

several games are way too expensive than somewhere else.

the saboteur costs almost 20€ here at gog and can be bought at origin for about 5€.

noone could explain that till now.
gog wont do it either.

its gog decision to make the price that high.
try to buy such games in a sale or somewhere else where it is cheaper.

A little clarification - it's not GOG decisions, but the rightholder. They are the ones to firsty dictate the price. There is a lot of small stuff like that people don't notice - legal contracts speficy a lot of things and not abiding to them can cause troubles.

Some EA games are more expensive in the US than in the Europe, 20€(20$) is the US price.

This. Dead Space is an EA game and is regularly on sale on Origin in Australia for $2.49 (reduced from $9.99), yet here it's on sale for $7.49 (reduced from $29.99). I can only imagine that it's part of GOG's deal with EA that they have to offer the game at a certain minimum full price and minimum sale price.

steam should be cheaper since you're really just leasing the game if you get it from them, on here it's yours, i think this is a reason there is a price difference.

Possibly. Without 'inside' perspective we can only speculate, and while I understand that people are not happy with some pricing... It's important to remember that could not be GOG fault.

Regional price is not better.
3 times difference between steam and gog :(

Weird, I got it on sale for 5$ from GOG. Just yesterday..
