So, Valve has finally released their in-game editor. And I couldn't be more thrilled.
I've always wanted to make maps since Portal came out back in 2008, but lack of personal time and the difficulty of learning Hammer, along with a lack of prefabs for some of Portal's common elements, kept me from starting. I mean, I've used WorldCraft, Hammer's predecessor, but the time and effort to relearn it wasn't something I wanted to invest. And, when it got right down to it, the time it would take to create a simple puzzle wouldn't be worth it in the end, I felt.
