It would make for a great TV series, and you can kick it off with this guy in current times. Maybe he loves to play the role playing games, and knows all the facts of every game there is to be played. Then one day someone introduces him to a new game call Ultima, but it's more than just a game, as he finds out later. Just like in the 1st game, he gets summoned to Sosaria to defeat the evil wizard Mondain.
Each game could be 1 season of a TV series.
Season 1 - The First Age of Darkness
Season 2 - The Revenge of the Enchantress
Season 3 - Exodus
If there are good writers and actors, we could get a few more seasons.
Season 4 - Quest of the Avatar
Season 5 - Warriors of Destiny
Season 6 - The False Prophet
Still lasting even longer, you can switch out cast, and bring back others that left the show. Then get even more Seasons!
Season 7 - The Black Gate/ Serpent Isle
Season 8 - Pagan
Season 9 - Ascension
I think it can work out, if done right it would be a great show. Oh details of the games I posted as season is located at the link.
I have always thought that PWI's flagship game, Perfect World, could be a wonderous anime movie. The factions mistrust each other but must work together to combat the Wraith threat. Young people are more willing to create the diplomatic bridges needed for their people to work together.
I first learned the Chinese elemental system in PW and I still like it. Lightning wielding flying Elven archer are both Metal and pretty "Metal", if you know what I mean.
