I wouldn't play Fief with 3-4 personally. Ideally 5 players (3 hours) but would do 6 players (3.5-4 hours).
I'd be up for that Pete if someone has it. I didn't pay for a board room ribbon and I'm not bringing it. Also, I'm with 3 other people so not sure how much I will be available. 6 player Eclipse is a bit long but do-able.
I got Fief with the expansions (but not the upgraded bits) from the Kickstarter but I haven't gotten to play it yet. Everything I read about it gets me more excited though. I like the old-school design pedigree, and I don't really get why nowadays "random craziness" is a bad thing even if it is a long game.
