...I just realized that I play next to no games where you have anything but human powers. Only gadgets and gear.
But I guess being a Space Marine would be kinda cool? Spitting poison, breathing toxic fumes, being able to sleep while still being on the move.. My only problem would be that a) I'd have to live in a suit for the rest of my (considerable) life and b) I'm not sure what happens to their genitals, but they don't get used much, I believe.. that would be a problem...
As a note.. what's with these captchas? I keep getting greek and hebraic letters!
