GameSpot reports that a man has sued Sony, Sony Online Entertainment and Sony Computer Entertainment of America, contending the company violates the Americans with Disabilities Act for not making its virtual worlds more easily navigable by the visually impaired. The nature of Alexander Stern's visual impairment isn't clear from the report, whether that is total blindness or partial blindness, or some other form of sight disability. But his suit, filed in federal court in California, claims that Sony has ignored repeated requests to modify its games - the suit seems to focus on SOE's MMOs - and that the realms Sony maintains here are essentially public accommodations as defined by the ADA. Stern repeatedly asked Sony for the addition of visual cues to point out destinations for gamers with "disability impaired visual processing." The suit mentions World of Warcraft and another game that, through the allowance of third-party modifications or other features, make their games more accessible to the visually impaired.
