Well, as the time of writing this I am learning in the 9th grade and I am 15 years old. I design games and I like learning new things. I found Counter strike when I was 8 years old. At age of 12, I found HL1. Before it was a 'nonworking' mod for CS. Yes, I know, now it is stupid. But I was that guy who told the truth to my friends.
Anyway I tried mapping before, but only at the age of 13, I tuned up my skills.
Also I am learning C++ at the moment. You know, Half-Life 1 modding. And I really like Xash3D - a custom GoldSource build. Looks good to me. I also enjoy playing GarrysMod and other Source mods like BMS.
I am quite eager to start creating maps for source.
PM me, if you have any questions, or just want to know something.
PS. I don't want to everybody think, that I know nothing, but I don't know everything. So... I know something....
