Dude, I have so many ideas for a map that its amazing, even to myself but..
I just got in from a 5 day series of runs. I am so tired its sickening but, this is the busy time and I must contend. Also, being on 56k has disheartened me to the point to where making a map, but never being able to play it to test even its construction aspects is sad.
Lastly, HL2 got boring with the 4,000th or perhaps the 5,000th toilet toss in my face.
I have however been giving thought to making something. A map named Killbox_Canyon. It would combine my worse idea for maps "Killboxes" with my hardest making idea, "Rocks"
The idea of a box canyon intrigues me. It might encourage me to do it. Also, the idea of making a map theme I hate, just to prove that a box can be pretty, is also a motivation.
