One thing for sure, Michael plays a lot of games.
I've forgotten more characters I've helped get through their adventures than I can count, but if I may, I'd like to tip my hat to three:
1. Gordon Freeman - Let me explore through his eyes a cold war missile complex converted into a massive lab, defied a totalitarian system, and drove a badass buggy and airboat.
2. Edison Trent - Explored new star systems, participated in interstellar commerce, and fought against an alien security organism gone wrong.
3. Altaïr ibn-La'Ahad - Explored the cities of the crusades, Damascus, Acre, and Jerusalem, in a struggle between forces that an ordinary person would never see. Possible by proxy through the mind of Desmond Miles, using his genetic memory.
These characters give me so much an experience, that it is not I who they should drink to, but to them I feel honored I was able to walk with them. Salud!
