Remakes are risky business. Fans may say they want to see their favorite games get a new treatment, but developers need to be careful, because a remake is easy to do poorly. Keep too close to the original, and people complain that it doesn't bring anything new to the table. Go too far afield, and it doesn't deliver the nostalgic kick that people wanted in the first place. It's a fine line, but following a few simple rules can make it easier to walk.
