At first I didn't know it was him because he goes by his real name on FB, but with further inspection of his FB page (yes, I stalk everyone who likes my stuff for some reason. I have no life) I found his YouTube, and when I got to the bottom of the YouTube feed I saw it all. Development videos he had made and such, all in the name of MexiCouger.
I'm 100% sure it's him due to multiple reasons, but this was the short story. Now he's making gaming YouTube videos, and he's going to start doing other things on YT as well (his videos are pretty good) As far as I'm aware he's done with the modding scene, and game development scene in general. The last thing he posted about it was a person project of his own unrelated to Quake and Halo by all means.
I just thought I'd let everyone know in case they didn't (although I'm sure I was the last to find out) xP
Here's the link to his YouTube anyways: https://www.youtube.com/user/Mexicouger/videos
I guess this was the first step of me wedging my way into the forums.. heh.. c:
