Game: Team Fortress 2
Date: Somewhere this week? Tomorrow or Thursday perhaps? In the evening hours (somewhere between 19:00 CEST and 21:00 CEST?
It's Free 2 Play - no excuse not to play!
Maybe something like Highlander mode (which has class limits, only 1 per class per team) with regular games (Capture points, payload?), or maybe Mann vs Machine (Humans vs waves of bots).
