Trying to make sense out of mmorpg's

[S.O]

OK
This might not be the best place for this question
but here goes - trying to figure out the main parts of any mmorpg (taking co as the example - coz i know co!)
made a simple drawing in powerpoint of interfaces (if u donno what interfaces are - they're logic distributions - and some more programming stuff)
now - its not fully detailed - but i want ur opinions on it.
most important - am i missing anything crucial?

now - what game stuff include:
ISystem - IScreen + IHotkey(s)
IHotkey - Activate, Enabled, etc.
IScreen - IChar(s) IMob(s) IItem(s)
IChar (the active user char - not other chars around) - IInventory IPosition ICommand(s)
IInventory - IItem(s)
IItem - Quality Type etc...
IPosition - Map, X, Y
ICommand - Activate, Enabled, etc.

what logics include:
well, actually, it includes the gaming map (maps and portals between)

thx for taking the time if u got this far

well you are right this aint the place for this most ppl like me are here to leech exploits and hacks...

Most ppl wouldent even understand what you have been doing,
now i see something that might be missing though what about that drop rates or drop roll for items?

[S.O]

now, drop rates and drop rolls are server side
i cant access that
