Yer all a bunch of noobs. I made my early mapping experience in Wolfenstein3D.
[TLDR at the bottom]
My start in mapping goes back to about the year 1999, when I got my first computer. Until then, the only games I knew were those in other people's computers. Most of them were DOS-based and Windows was a rare novelty to me. Along with a crapload of demos and shareware versions of old games that came bundled with the computer there was a shareware version of Wolfenstein 3D (shareware was just Ep1). I had played it before so I knew that was one of the greatest games ever, but I couldn't figure out why the rest of the game was unavailable (as in, episodes 2-6 removed from the shareware version).
One day some acquaintance of my father brought me this unusual-looking disc, all black except for the lone words "Wolfenstein 3D" in cyan on it. Maybe this disc had something of interest - perhaps even the missing parts of the game - so I grabbed it without a second thought. Turned out to be a huge collection of folders and files (that now I know was internet-type content, but I had no idea at the time). Lots of folders with custom Wolf3D mods (most of them just the content files, it took me a while to figure out why there were no playable .exes in there and how was I supposed to make use of them) and some folders with extra stuff that wasn't games at all. Names like "MapEdit 4.5" and "MapEdit 7" got my curiosity, but I still didn't even associate that with the idea that game content could be modified; plus the .exes in there failed to run. I left those uninteresting non-funcioning programs aside and proceeded to get my hands on the "playable" games, each one of which turned out to be some kind of hacked version of the game (custom content, but I didn't know) and quit a bit bitter because none of them were the full game I was looking for.
But what were these dull-looking programs? It took some time but when I got them to run they all showed these big square graphs on a black background. What the hell was this? After some fiddling I noticed one of them looked a lot like the floor plan of the first level in Wolf3D. Matter of fact, the next one also looked a lot like a floor plan of the second level, and the next one like the third. It didn't take long to make the connection, and I got my hands to it right away.
I started by making small "convenient" modifications to the existing levels, but after a while they got boring and I started making my own levels. Basically by putting all the placeable stuff I could find in the editor. I made 10 levels for the whole shareware episode. Let's say I called it WolfenStu
. They were crap, but I still thought highly of them. My friends also thought they were awesome, so shortly after I made another 10-level pack - WolfenStu 2. Then came WolfenStu 3, 4, and 5. Each one meaner than the last as I gradually learned the subtleties of the W3D engine. There also was a resource editor, so for pack 6 I started drawing new sprites to replace the knife with a lightsaber and the gun with a hand throwing a red brick.
Unfortunately, I lost all of these the next time I had to format my hard drive. I think there might be a possibility of finding one or two, though. I'll look for them.
Fast forward a few years to when somehow, a Counter Strike disc came into my hands. It came along with a bunch of boring multiplayer games that seemed to use the same engine (HLDM, Op4, etc. plus Redemption which I thought was crap for not being multiplayer, despite me not even having internet access). I no longer have that disc. At the time, maybe you knew someone that knew someone that knew someone that had a cd burner, so I had them make me a copy so I could loan out the copy without risking the "real" disc getting damaged. Ironically, I eventually lost the "real" disc and I was only left with the copy. Which unfortunately was one of those cheapo no name blank discs that look the same on both sides, and after a while the plating started peeling off and no longer reads. On the other hand I somehow ended up with a HL disc. I didn't even care about it, everyone was playing CS at the time.
One day a friend said he knew someone that knew someone that knew someone that somehow had made his own map for CS. Nobody believed him, but I immediately started searching the internet for some form of level editor (whenever I was visiting someone with internet access) and eventually came across some program referred to as Worldcraft that I couldn't figure out. I kept it, but also kept looking for easier and user-friendlier alternatives (that turned out to be worse).
I eventually went back to Worldcraft to try and make some decent CS map to play with my friends. And for years, my only mapping resource was random google searches. I only came across TWHL in 2009 and I immediately registered. Most of the mapping sites I had visited before were all flashy looking with ads and popups. I loved TWHL because it was easy on the eyes and didn't look massive, more like that small bar around the corner where everybody knows everybody.
TL;DR: First tried out mapping for Wolfenstein3D, until I moved to Counter Strike. Didn't play Half Life until about 2006-7.
~Your advice to future mappers/current mappers?If somebody else could do it, you can do it too. Game makers don't do magic, there is always a way to do things.
Also, less is more.
