Great idea for a thread.
About the only game I play online regularly is Call of Duty.
I dabble in Combat Mission, Gary Grigsby's World at War, Vietcong, The IL-2 series, Silent Hunter III, Bull Run, Sid Meier's Pirates!, Mount&Blade, the Madden Football series, Tiger Woods Golf, Dungeon Siege, Rome:Total War, etc.
I'm currently trying to find a copy of Freespace 2 for my five year old, he is a space junkie (he loves Lego Star Wars).
My gaming roots go back to the Avalon Hill/SPI paper games of yore.
ASL. There are no other Avalon Hill games. :)
Welcome to Freeping Gamers! feel free to use this thread to get a game going somewhere.
