I just found out through Facebook that my cousin through marriage, Blair Leggett, a computer systems analyst at Zynga (yes Facebook games) who used to work at EA, has ported the entire game of Ultima IV so you can play and save in any Flash friendly web broswer! He has made a few improvements as well as added some features that were introduced in Ultima V.
Just by having the article, posted below, in PC Gamer has increased the traffic to his website by 280%
