...about this game. It is stellar. Story, voice acting, gameplay, all are superb. I knocked it down a little due to technical issues I encountered. I had to reload a couple of areas as frames started dropping with nothing going on. I don't know if GOTY edition is the only way to buy it as challenge rooms are all it adds to the game (something I didn't care to bother with). If you haven't played it yet it is a must buy/play.
