... I can really live without the predator challenges. I hate those challenges and they stopped me from getting 100% in AA and now this. Combat challenges I can live with but I suck and hate the sneaking around stuff with the clock ticking away, just not good under that type of pressure.
Also, I can live without the statues and art - throw in more story and keep those things that I look at once then never go back to. Just my 2 cents. All in all, game is awesome!!!!
