Sybex should have better informed their customers about the limitations or did they? Also you got the Sybex book and people who bought from Conitec did not. You should have looked up the official Conitec (GameStudio) website before purchase it from Sybex to see differences. Not just buy and later realize you bought a cat in bag or how is it said ^^

IMO I believe that Conitec thought about their position and therefore made a deal with Sybex to get even more attention and money for each Sybex edition sold or something like that.
