There have been several other threads posted on this subject that can provide better detail on the pros and cons of the subject, but there is overall one key point that you need to take into account, and that is not the high polycount of the Poser models. Most Poser models are licensed for use in stills and animations. You may not redistribute the models without the prior approval of the original content creator, nor can you redistribute modifications (such as reduced resolution versions). There are some free models out there that may make an acceptable base from which you can work. One such example would be the Project Human figures which exist under an open source license. But other figures, such as the DAZ figures and the stock figures that come with Poser are out of bounds for such modification and redistribution, whether in .X format or otherwise. Such restrictions are not limited to the human figures alone, but also apply to the clothing articles as well. You may find some free items that are not restricted as such, but the majority will not be redistributable, even in modified form. There are a few games that have worked around such limitations by rendering images and animation frames inside Poser and converting these images to animated 2D sprites. I've even seen one that somehow manages to cleverly mask those 2D sprites such that they look nearly 3D. Something like that seems to fit well within the licenses of the commercial figures. There are other options available on the market, however. For example, there are a couple of DarkMatter content packs from The Game Creators which are already in .X format (though they are of very low quality) which may be used in your own project without restriction. There are also more and more content packs becomming available at sites such as GarageGames that can be of downright stunning quality. Perhaps not on the level of Poser, but then, by the time you reduce an 80K poly model to about 3K polys for use in a game, it won't be of the quality level of Poser anylonger either :) Hope this info is of use.
