He may or may not be a decent FPS player; given his falling off the map so quickly, that's actually kinda doubtful. Still, he's already better at it than I am; well, anyone would be better at a FPS than I am!
But he does appear to be a decent person; he was willing to give the Goblins the benefit of the doubt, but once he saw they had a human female captive, he decided to intervene, and at least had the smarts to realize that this meant he had to wipe them out; there only being the one of him, he can't afford to leave known enemies behind.
The general comments appear mixed; we'll see how this goes. Pity so many chapters are missing.
