I just finished Riddle of the Sphinx after 5 wonderfully grueling days. I must tell you that it is the ABSOLUTE BEST adventure game I’ve ever played (including such favorites as Riven, Grim Fandango, and Obsidian). The game designers have done a magnificent job with the artwork and renderings, and the puzzles are tough at times but totally logical. GREAT JOB, and kudos to you. I’m already eagerly awaiting the sequel.
