Epic did something very right with Gears 3. They gave themselves the ability to create dynamic playlist that allow them not only to change the weapons on the maps, balance weapons, change starting weapon but also alter the entire experience so Gears of war feels more like a standard shooter (i.e. Stay Frosty). Regardless of your feelings for a given playlist (I don't care if you don't like the new playlist or changes) that fact that they built this into their game and have constantly been providing new experiences to their Community is way more than most developers would do. Think about the time and effort each playlist requires, they have to play test, tweek and monitor every one of them to ensure the best experience they can for their players; and at not additional cost. And yes the changes to playlist (combining warzone / execution) might upset some people (they did had the smallest populations), but the majority of the time these changes are great. My hat is off and wallet it open to Epic, here it to a company who want to provide a real experience for their community. I guarantee other shooter will have to copy this dynamic approach to MP if they want to stay in business.
What kind of game type do you want them to create next?
