I don't know how long you have been using FPSC, but it looks like you joined the forums yesterday. I will go ahead and make the assumption (bad word, I know) that this is how long you have been working with the engine. So my advice is that you will get into any piece of software what you put into it. If this software does anything well it is that it teaches you how to create games. The same lessons learned here about poly counts in scenes, triggers, dynamically loading and unloading entities, scripting and overall basic techniques will transfer to any game software. I did exactly this. I still use FPSC to create fast and fun free for all shooters for my friends. But I primarily work with UDK. But I would not know the slightest thing about programming a game if I did not learn FPSC. I even use FPSC to quickly try things to see how they look and feel. But UDK, CRYengine, and FPSC all have one thing in common...You have to make the game.
You mentioned just changing some things to make it feel like accomplishment. UDK does not allow this for commercial games. In the EULA you have to write all the scripts from scratch to be able to sell a game in UDK. FPSC does not expect you to do this. That is a huge benefit to FPSC
I would suggest explaining what you are trying to accomplish, what you have so far, and I bet the people here will have no problem helping you fill in the blanks.
Quote: ""Why do people bring up UDK and CRYbaby engine a lot? I could make a crappy game with them too. lol!""
100% true. I'm sure my first 50 games in any engine are pretty terrible. I'm even willing to bet people will find my project I've been making for 2 years now "crappy" as well. But, I'm willing to live and learn and apply that criticism to the next project.
Here is a tutorial I wrote to help new members. I do this entire level using only stock items and scripts. Nothing new or changed.

I also do a simple game here in video (warning: large file sizes)
