Thanks for the insight guys, tis a difficult choice...
Quoting "Niborius"
Btw, is it allowed to use source textures? I see you did that
Yeah, I used a few Half-Life 2 textures and sounds (and might use some music also). Is it allowed? No, but its not like there going to undertake legal action over this and I'm not really interested in publicly publishing this game anyway (at least not anytime soon), if I ever do publish this game then I'll be sure to remove the Valve content (and content I used from other games)
