What do you guys think is the optimal size in pixels for the "main" continent?
How long is a piece of string? Really this comes down to personal taste and what your trying to achieve with your overland. What is the point of overland in your game? How is it to be used by the players? How .....
I have played games that had huge overlands with over 4 million rooms, for me personally i think vast expanses of nothing are boring and i dislike games that use overland or in the case of picture games expansive maps of nothing as filler that i need to travel across to get anywhere.
EDIT: Also, is it possible to add any kind of description to an overland room? such if you're walking on a road and there is something next to it, or a landmark or something.
Yes its posible, there are already the beginnings of what could become descriptions in the code, where one sentence is displayed for each sector type."You are travelling along a smooth stretch of road.".

You are travelling along a smooth stretch of road. The sun continues on its wes
tward journey accross the sky, increasing the length of shadows cast by its eter
nal warmth. A lively breeze cools the area and thick, grey clouds mask the sun.

The overland is the perfect place to use dynamic descriptions that you can pull together on the fly to display information about whats happening. The above is output from my overland. The dynamic descs are only in their infancy so do not do anything more than show the default 1 sentence and the weather for now, but as time permits i will extent it further.
In my game the maps are somewhat smaller than what is seen in many game, being only 100x100 rooms and there are 9 maps in total. I use these maps as you would in a picture game, they are the primary leveling areas, i have done away with the random spawning of mobs and have the maps full of resets instead and only have a a couple of conventional zones, the rest will be instanced quest dungeons.
So as long as your main continent fits in with what your trying to achieve, it can be of any size necessary to fulfill the vision you have for your game. Just dont leave them great vast enmpty spaces of filler between zones, give them some life and some purpose other then that.
