usually if you want to do a cutscenes, you should aim for a MACHINAMA Type Cutscenes. Currently in My Game, Deathly Silent, I am trying to include cutscenes type up what every character will say,and do, then find people who are willing to help, give them the script, then make the level an "arena", and tell ur "actors" when to go on line, and which server to join,then you must have given them the script,and a start time so so everyone starts at the same time...
I hope this helps
