I played Titanfall at the Eurogamer Expo in September. It was awesome, despite the "low" number of players.
6 human players per team, each with their own Titan. The Titans can be human piloted or can be left to AI control (they can follow you, or guard a location, etc.)
Plus there are 12 AI characters per team.
