@HelloRaptor I think one of the reasons I liked the Secrets of Power series as much as I did is that I'm a sucker for 'training' novels in general. The theme of some random corporate stooge gradually immersing themselves into a different world, learning the basics of what it is to be a shaman and then a very powerful one appealed to me.
Shadowrun 2nd Ed was my system of choice. Man, the hours I spent with an MS-DOS-based calculator trying to squeeze every bit of cybernetic gear I could into a character without making his body fall apart. It was the most fun I ever had simply picking stats for a PC.
