change 'within a year' to 'perhaps in a decade ..or two'
No one knew how to do it when Kelton figured it out.
There were no other online 3d-games ..anywhere.
Even Wolfenstein/Quake/Duke Nukem came after AW.
As for online air combat .. Fighter Duel ..came well after AW.
And it was 1-1.
AW was 30 people flyin an fightin in 3d back when text-based adventure games on BBS systems was the norm.
There wasn't even a 'web' then.
Internet Explorer was still years away, much less the watershed that AOL was to 'normal' people who had never heard of the term 'online' much less 3d gaming
