Heya...
I wrote a white paper for Threewave about 6 months and it was just recently published @ GameDaily.com's business section. I've reposted it at my website (with permission) and figured I'd share it with you guys.
You can check it out here.
I wrote about 75% of the document and did the majority of its research. Threewave specializes in multi-player design & content and wanted to have our ideologies of a great experience written down. I researched the experiences for about a week and spoke with a number of people from different studios to get their thoughts on multiplayer as well. The article is a culmination of all ideas, thoughts, and theory on what makes for a great multiplayer experience.
Enjoy!
