He's just saying what kind of stuff would be cool in the arena if it was in Fable2. I think that it is okay, if he made the title more like....If there was the arena in Fable2?.....
Anyway...I think it would be cool to be not just a combatant, but and obstacle in the arena. Like you are the last stage in the arena. You have to fight a hero or two. OHH I JUST GAVE MYSELF AN IDEA TO POST IN THE "IF YOU COULD HAVE ANYTHING IN FABLE2 THREAD!!! (and I know about the caps lock thing)
