I'll address some back comments and include my own thoughts. First off, if someone is genuinely stabbing 8 times, I'm sure their game is basically over. I find that the best way to play is to make tactical decisions on when and where to stab. I tell the truth 90% of the time and lie 10% and make my lies count.
Secondly, if you're merely lying to someone who never really had the opportunity to trust you, it's not much of a stab and in 1901, you can't really stab unless you really *really* dupe the guy who's totally committed. I will make an alliance last until I can afford to ditch it, and if I can't ditch it, I'll keep it. In any event, you cannot possibly win a game without stabbing someone and maybe even two people. If you and an ally are simply "racing for 18" holding hands, then you're playing the wrong game.
I remember the first time I stabbed a guy. It was glorious and fun and I talked him into staying my ally for another turn and another stab. But then again, it was at a convention and someone I didn't know. I also remember the first time I stabbed a good ally. It was hard to do the first time and I tried talking myself out of it for a while. The first real stab is hard to do but it gets easier over time.
And yes, everyone loves Eden. Right up until they stab him or he stabs them.
