People aren't playing because of the relative difficulties involved in hosting a game. You can't just jump onto a server and have a bash like in the HL2 mods.
No, instead you have to contact the people that want to play, organise a date and time, reshuffle the teams because one of the players is Axis, and we thought he was Allied, postpone because the EiR webpage is closed for maintenence, and then after all that have a player DC in the middle of the game.
N.B. I know it's not actually that bad, but I felt like ranting.
