While you may not be able to use it for FPSC models at all, way to high poly for that, you still could use it to create loading screens and such. So here's the info on the deal.
September 1-4 E-Frontier, the owners of Poser, are giving Poser 5 away for free, throught their content store. It's not the newest version, but it's not old either, the newest version is Poser 6, so this is a good deal. Also I do know some of you use more then one engine (as I do) and perhaps it can be used with one of your other engines also.
If you want to get into character animation and so on, this is a good chance and it's free.

But beware, even though Poser 5 does have a good selection of characters, animals, clothes and other items, you may end up spending a lot of money on addition content, if you like Poser.
To get an idea what Poser (with additional items) can be used for check out these games, most the gfx have been created with Poser 6 (but there is a good deal of my own design in it also): DragonMania [href=http://www.gamefun4u.nl/page11.html ]http://www.gamefun4u.nl/page11.html [/href]and Caveman's World
