Steve Jackson's Ogre looks to be a two player game! BUT, some other LONG games i own that we could try on a week-end (all day) are:
Descent: Journeys In The Dark (FIRST EDITION) (2 - 5 players)
Gears Of War (1 - 4 players )
Starcraft: The Board Game (2 - 6 players)
World Of Warcraft: The Board Game (2, 4, or 6 players)
...i have NOT played the above games before (with the exception of Warcraft), so we'd have to pre-learn the rules before we try any of these. Warcraft, as i remember it was a team game that involved a LOT of math...
Co-host's (AvrAm) note: To smooth out the bringing of stuff, let's engage in the comments section, so we can prep what to bring. IN THE COMMENTS; name two long-playing (3-12 hours) games you would want to play.
