Ok, so I stumbled over here due to a forum link from a very old site. Both TWHL and RUST were linked in my signature block.
RUST seems to have died or gone Wiki with no contributors.
TWHL seems to have expanded exponentially... well done all.
So the first thing that caught my eye was the Verc Archive. Long before Source Tool Kit there was Hammer, before Hammer there was Worldcraft and what a right royal pain that thing was. I still remember making my first room and banging a crowbar against a steel shelf.. How cool was that
Anyway since I am on a nostalgia trip, I had the great honour of speaking to a lot of the people listed on the Verc tutorials. A few of them work for Valve these days, others have (like me) dissappeared into mapping and design obscurity. The one thing common to all of them was their love of Half Life design and their ability to push the engine to it's limits.
Take Care all.
