Yes, that would enable you to do great things with the engine should they modify the source code for v1.
With all of the new features added to v109 though, commercial games are possible without modding the engine.
All you really need are good FPI scripters and the artists for making your custom models. (some people here can script anything that is possible in FPSC, but there is a $1000 commercial license for X10)
However if you have the cash to get things done, then...

There are too many to list, so head over to the models and media forum and pick your favorites after viewing their work.
Some of these people may already be to busy to help you, but there are many others who can probably help.
Oh, and don't forget the new TGC store that will be incorporated right in to the editor.
In a couple of weeks there will be hundreds (700+ now & growing) models to choose from that you can buy at a very low cost.
There has never been a better time to develop a commercial game with FPSC than right now.

FPSC is the best solution out there for making low cost FPS games.
Yes there are cheaper ones, but they are harder to use.
Yes there are more powerful ones, but they are harder to use.
The ease of use will save you countless man hours in development and get your products out quicker.
Also, don't forget the license for FPSC, which is far better than any of the competitors. (no license or royalty fees for FPSC, but there is a $1000 commercial license fee for x10)
FPSC is the most user friendly FPS solution out there, and the features are getting better by leaps and bounds.
I plan on pushing FPSC to the limit on my next release, now that we have those scripting variables in v109.
I should have a trailer for my new game up within 2 weeks of the release of the stable v109, then you'll FPSC's new features at work.
I'm working on all of my custom scripts now using the beta version of v109 to get a grasp on these added FPI conditions/actions while we wait.
Team requests are not allowed here in the forums, but if you are serious about making a commercial release with FPSC (only a few of us here are/most do it as a hobby), then I am sure there are a few people here that would be interested in joining forces in that endeavor.
