Forget Xbox, get a Wii. - Off topic.
Actually I was going to post and ask why people keep comparing FPSC capabilities with games that have millions of dollars invested in them. Why do people think that one person sitting in their basement can create a game as competitive, visually stimulating, and as high-performing as those found on Xbox or Playstation etc, without any of the skills as the team of people who made those games? Are these the same people who are upset that Guitar Hero doesn't play at all like a Phoenix Strat with a scalloped neck?
The software is what it is. Take a lesson from the Wii. It's about the gameplay. Design a good game and people will forgive graphic shortcomings, or a framerate of 24 rather than 30. Use the tips'n tricks guide to help with good puzzles and timely dialog. Anyone can draw the segments and put some weapons down. Be honest with yourself, what makes your game different? To this day I still play Galaga, or Galaxian, or whatever it's called. It's a good game regardless of graphics, sound, etc.
If I see one more post saying..."How do I make a script to make my objects float in water like in Half-Life?" I'm gonna scream. Quit trying to copy others!
