Just my thoughts on sequels.

Is it just me, or does it seem like a lot of games try and play it safe by keeping the same game formula and just making the game harder? A perfect example of this is Dead Rising 2. They even rewashed up some of the same songs from the original game, though they didn't go with second.

Some games have mashed up the gameplay a bit, like Resident Evil 3 to Resident Evil 4. But then in 5, all they did was try making the game harder and keeping the exact same gameplay as 4, except with a partner.

Just seems like game developers are starting to fear changing the game, though sometimes a change is needed.
