yes, i like playing in the leagues because you get to know the same group of players over time, it would not be the same if they were anon.
@Maniac, As i understand it, that hard and fast rules for league meta-game are
- you may take league position into account when deciding who to work with (or who to stab)
- you may use knowledge of a player's previous behaviour when deciding who to ally with (ie if the jerk stabbed you in game 1 you're allowed take that into account in game 2/3)
for me this has meant (in the first season i played) agreeing with 2 others to a 3-way draw in game 1 (4

for each of us) agreeing with a different 2 players to a 3-way draw in game two - on the basis that i'd be on 8

, and they'd have moved up from 0 - (but i stabbed them and ended on 16

) - losing every other game in the league because everyone was out to get me as i was on 16

...
It was a meta-league strategy to aim for 16

and play my first two games out knowing that i would be screwed over by everyone in the last two games.
I specifically allied with different players in the second game so even if things went sour they would be strong and the players i was tied for first place with (after game 1) would be weaker...
i see this as playing the meta-game.
i think league positions should be something which every players can see clearly at each point in their game. (on irregular occasions i have posted league positions on global chat - mostly because i wanted to use the information as leverage in private negotiations...)
