Kinda understand that. I'm currently working on a short story involving a character who kinda reminds me of Wolverine. The way I'm writing it is like playing a video game, looking at each tactical situation and working out how the character responds, how he thinks. Although I'm currently stumped, with only 3 weeks till the submission deadline, and that's causing some stress, I do find in general that it's pretty therapeutic, getting everything out. Through the mind of someone whose sole purpose, for the moment, is survival--personal survival, and survival of his species against an aggressive alien invasion force. Someone who is intellectual yet has the ability to be a killing machine. A special forces combat veteran with the scars and opiate addiction to prove it.
