Thanks. Here is the translated version(it's translation is not that good): "More about setting Obi-Wan for the PCWednesday, November 29, 2000 [One year before the release of the game] at 12:16 pm by sAiOtEkOn Gamestar.de there is more information about the setting of Obi-Wan for the PC. GameStar.de has already reported that LucasArts has discontinued its action game Obi-Wan. Now, Simon Jeffery, head of the company, has clarified some of the reasons in an interview with Gamecenter. So the game is not the successor to the classic Jedi Knight expected by PC fans, but something completely different and would have disappointed the players; GameStar had previously criticized the game because of the emphasis on overly complex sword fights and Tomb Raider perspective.Jeffery also says that Obi-Wan would very well run on fast PCs - in the point he is dissatisfied with the official press release, which had shown this differently. However, it is unlikely that average computers would have displayed the (in preview versions not very impressive) graphics properly. After all, between the lines is to read that for a real Jedi Knight 2 is quite hope." So from that I can make out(Or maybe speculate) that Simon Jeffery(The CEO of Lucasarts from 2000-2003) cancelled the PC version because:1.It might have disappointed jedi knight fans. 2.I think The game's PC version wasn't running well.(The Wikipedia of Obiwan game refers to this as the reason of this game's cancellation) Unfortunately it still didn't answer this question that why this game was so graphically poor.
