If you don't like that, then try renting it first before daring to buy it.
It's different. But a good number of people DO like that it's different... it makes it feel like it dropped the ruined franchise of Silent Hill and moved on.
...however, it's that same difference that makes others despise it. It ain't a bad game, the bad talk and low reviews come from disappointed fans that wanted it to be like Silent Hill 2.
...it's not, but it's still a great game in its own rights. Take it as you will.
