All depends on how you design the tables too.

The parallelism for one thread per player would be very nicethough.

However, I'm not limiting the database to just SQL, it'll do arrays, hash
tables, and binary trees too.  All at the same time too.  You can have
multiple worlds each with a different database backing and each of the
rooms, mobs, objects, etc lists in each database can be different too.  I
can do that without extra complexity due to the way I've designed the
system.  Saving will be interesting though. ;)

'void *' is cool.
