Trilarion: What used game market? There is none anymore? Have you ever seen an offer for used GOG games? With going all digital, this is over. There is only piracy left to fight.
Hardly. You ought to know that the PC retail market here in Germany is still much stronger than the digital market. The US and Australia are really the only two markets where PC digital distribution has a dominant hold - in the US because PC is now pretty much a minority compared to the consoles (Xbox very much rules the roost there) and Australia because digital is much cheaper than retail. I've heard the UK quoted often as well with the lack of games available in Game, Gamestation et al., but everyone I know there buys their games from Amazon and Play.com.
Obviously they've been trying to strangle the used PC games market with account binding, but evidence suggests that all this has achieved is a sharp reduction in sales.
I personally still buy plenty of older used games, for PC, PS1, PS2 and PS3.
