PCS should focus on Silent Hill 2 as that remains best in series.
I completed Silent Hill, Sillent Hill 2, Silent Hill 3, and got quite far into The Room (Silent Hill 4)
..and passed on the rest, as they were created by 'other' companies and received less than favorable reviews.
The Top 3 characters: (in no particular order)
James Sunderland
Maria
Triangle-head/Pyramid-head
The screwed up monster nurses (for want of a better name) are popular
Personally, i'd be up for a Triangle-head/Pyramid-head.
