GM_Forest2008 will be bigger and it has different weather and stuff, but I let the people build the temples/houses/whatever they want themselves. They have the wiremods and stuff so they can build anything they want to the map.
Thanks for your comment :D But remember after playing gm_Winterforest, that gm_forest might not feel so good after that. Because gm_forest I released on June 1st 2007 and the winter version on December 1st 2007. So there quite a difference in the performance and displacement work, but even though, the original map is what I will always prefer.
