Quote: "1) What are the limitations of FPSC? i heard something about 50 levels maximum... is that true? what else is there?"
I've never seen any FPSC game which had 50 levels. I think you'll find it a challenge to make 50 full size maps of consistently high quality.

Quote: "3) Is there a limit to texture sizes and details for walls, characters etc?"
Texture size limit is 512x512 for segments and 1024x1024 for characters.
Quote: "4) I take it FPSC is DX9 since there is a separate DX10 version. Can DX8 games be made?"
You are correct. FPSC is DX9. There wouldn't be any reason to create DX8 games now. DX9 is the baseline.
Quote: "5) How do i make characters?"
Get hold of Milkshape3D and a paint editing program then download the FPSC pre animated bi-ped for Milkshape from these forums. Then read the tutorials available on these forums. It's challenging at first but when you make the breakthrough the possibilities are limitless.
Quote: "6) How do i make textures?"
Download GIMP for free then learn how to use it properly. As stated earlier textures will need to be made in either 512x512 or 1024x1024 resolutions.
Quote: "7) How do i make levels and do all those sorts of things?"
The FPSC map editor and ease of implementing your own custom content are 2 of the best things about the software. There are generic WW2 and SCI-FI assests available to you out the box.
Quote: "8) What else do i need to know?"
You need to know that not having this sofware is the only thing preventing you from making a first person shooter that until this point you've only been able to imagine being possible.
Basically you need to make a choice right now. Buy FPSC and become a game developer or continue reserving that area of your mind for dreaming.
Your coming at a time when FPSC is so much improved from what some of us have had to use when we first used the product that I can't see you being anything other than blown away by it.
