a) Everyone is level 90. Advantages - everyone is powerful and can ignore most physical threats they meet, but it would also trivialize many possible quests or encounters except those suited for their level.
b) Everyone plays two characters, one at level 90 and one at a lower level. Level 90s focus on different aspects of the game than the lower level characters. Might get chaotic.
c) Everyone is level 50-70 or thereabouts.
A handful of characters start in the same guild, perhaps only the GMs and everyone else joins up as extra support, or everyone is part of the guild.
I'd like characters to be more like Akatsuki, Nyanta, Shiroe, and Naotsugu than Krusty or Soujirou. The former group are veterans and may have a few raids under their belt (or not at all) earning them a special item, but otherwise they're just like any other player of equal experience. Characters may have an uncommon but still generic title or subclass, but unlikely to have classes like Sword Saint or other unique rewards that the most powerful and renowned players usually have like the major guild and raid party leaders.
Edit: One question - if we do move the setting from Japan, what do we rename Samurai and Kannagi?
I'd personally prefer A or B, leaning toward A. I'd also like to point out that both the show and the light novels point out people having difficulty fighting even monsters 60 or 70 levels lower then them simply because it's now 'real life'.
Personally I'm planning on being in an American guild to start and deciding, along with the guild master, that it's not safe or practical to try and make it home and I should join a local guild for support until/if things change. Don't worry, he'll get attached fairly quickly.
I'd like to point out that Soujirou earned his special title in the Tea Party, which is also where they all got their Griffin whistles. For that matter the appearance changing potion Shiroe had was part of a promotional event, you just had to have been playing at the time to get one. We're not talking about having a dozen titles each or our own guilds, or even top tier gear, but a max level character will
pick up such things just from being around that long. That is
just like every other max level character. It's the personalities, goals, and the focus of the show and the books that makes them stand out... well that and being led by Black Heart Glasses. On a side note some of the title subclasses just require you to meet some goal, others can only be held by a limited number of players at a time, they are not all created equal. So being a Dragon Slayer (which is not number limited) is a lot different then being a Sword Saint (which is).
The standard form of the Samurai is Pirate, but Western Europe (which is the server region listed) uses the Paladin. The Kannagi is the Medium standard but Western Europe has the Exorcist instead. Furthermore the Cleric is replaced by the Templar. If
we go by the Official
alternative class table seen here.
On an unrelated note, in the light novels Shiroe mentions that there are "about fifty" subclasses, but that he doesn't know them all. He also states that other servers have their own, some of which they make up entirely rather then re-skinning. Just a side note.
