Yep. In addition to the options already listed:

- Marshal.dump and Marshal.load will store an arbitrary graph of Ruby 
objects (that is, the object plus all the objects it refers to) to an 
opaque binary file. Some objects cannot be Marshaled - e.g. File/IO 
objects, procs, and any object with singleton methods

- There are plenty of libraries which will store your objects in a SQL 
database, the most popular being ActiveRecord, but there are many other 
options including Sequel and DataMapper.

In this case, you need not define attributes in your class at all, 
because they are added at runtime based on the columns in the database. 
That is,

ActiveRecord::Base.establish_connection(
  ... database connection params ...
)
class Game < ActiveRecord::Base; end

is all you need to access a table called 'games'.

Of course, sorting and searching are bread-and-butter to a SQL database.

HTH,

Brian.
