Amnesia: A Machine For Pigs Could've Been Much Harder. In a lengthy and fascinating post-mortem, designer Peter Howell goes over the game's design process, noting many areas where developers The Chinese Room differed from series creators Frictional Games. It's a great read, check it out.
I played this game for about 5 minutes before tabling it indefinitely. I don't know, it was probably more than 5 minutes, but I just wasn't feeling the excitement for it right away like I did with The Dark Descent. I haven't given up on it completely though and plan to log at least a few hours into it before completely writing it off. I also have many other games in a holding pattern lately, so I suppose it's a personal priority thing in general for me, too.
