@Keeper: Welcome to the wonderful world of
The Game Creators! This community you have entered into is like no other, you'll find tons of free stuff here on the forums, friendly help and advice, and a crowd that (usually

) will listen to your ideas!
BTW, let me compliment you on how
nice you sounded in your post. Most new members have no regard for manners or just sounding nice. You are different from that, and I, if not, all of us, appreciate that.
Quote: "1. How much customization (through code, importing created character designs, etc.) is permitted in FPS Creator? "
I'm not sure if there is a limit at all. I think your imagination is the limit here. FPSC already has lots of features. You can increase the power and capabilites of those through coding, or you can code your own. You just have to
know the code. If you buy DarkBASIC Professional, don't expect to be able to re-write the entire engine for your own needs right away. It takes time to learn a computer language. FPSC also has an easy scripting language and there are plenty of resources to learn how to do scripting. As for characters, you can make your own. Not just characters, but
anything. Room segments, barrels, tanks, computers, anything you want. This also takes much time to learn but the reward will be worth it if you plan on being in game making for a while.
Keep in mind that FPSC does have limitations and you won't be making the next
Call of Duty or
Halo, but you can still make a super-awesome game and you'll certainly have fun with this engine.
Quote: "2. Are DarkBASIC Pro and FPS Creator compatible with one another?"
Quote: "If im not wrong,FPSC is built off DBPro"
Yes, the vast majority, if not, the entire software is programmed in DarkBASIC Professional. The code can be compilied with free upgrades and supplemental extras provided by TGC. I haven't been able to compile the code because I cannot find which upgrade extra's pack includes all the necessary DLLs. I am missing one and I am always running into the same compile error.

However, it is absolutely possible, as many people around
have and still
do compile the source code.
BTW, source code for the latest FPS Creator update (V1.1.9, or v119 as we call it here) can be found on the FPSC Google Code board. I can't provide a link because I don't have one on hand and don't know where it is

However, someone should be able to tell us where it is. If I can find it, I'll see if I can post it here
Quote: "You can design your levels in FPSC and export them to then load into DBPro for further development..."
Wow, I did not know that. I'll have to look it up!
Quote: "3. How many allies and enemies can be on the screen at one time? "
Not many. However, if you use a "mod" (a source code modification, which you can do your self as described above), you can increase engine speed, which allow for more characters.
Quote: "4. How many and how long can levels be?"
You can have up to 50 levels and they can be as long as you want them to be.
Have fun!
