Well, when you compare it to 1, 2 and 3 it does look like a crap game. But The Room wasn't even supposed to be a SH game. They just slapped sh4 on there to make more money. It was supposed to be related to SH but nothing to do with the series, like Resident Evil: Survivor, or Outbreak.
I don't think SH4 was that bad of a game, it wasn't terrific but I don't like how people bash it and say it's the worst game ever.
