This is a continuation of a discussion on Preliminary Objectives (SotT Optional Rule) which was thread-jacking a different topic for a while. The fact is that these unbalance the game in favor of players whose PO happens to bring them closer to accomplishing the Secret Objective they draw afterwards. Obviously there is already randomness in the game that will tend to favor certain players (map setup, Domain Counters, combat rolls, etc.). The question is, where do we draw the line at what is fair and what is acceptable
The thing about POs and SOs is that they should be considered bonus points and not your only objective in the game, which is probably why you're allowed to claim a PO or an SO on the same status phase in which you claim a public objective.
Unless you are playing with the Age of Empire option, the winner of the game will nearly always be among those who accomplish their SO. The major alternatives are either to go all out and try to accomplish one of the instant victory Stage II Publics, or seriously hamper anyone who succeeds in their SO-- which generally requires a cooperative effort.
TI has HUGE luck factor associated with it, somewhat depending on what options you're using. The political and action cards alone are things where a player can get extremely lucky or unlucky. Sometimes your PO or SO works perfectly with your race, sometimes it doesn't i.e. 5 Dreadnoughts and the Lizix Mindnet. Luck is just something you have to deal with when playing TI, the combat dice alone have made me lose battles when statistically I should have won. 1 Hostile Local beating 2 invaders, then beating 2 invaders again with Gen Synthesis, sounds improbably right? Didn't make it impossible.
The things that may seem "unbalanced" are actually what make TI fun, when randomness sometimes beats out common strategy, there's a fun factor to it. I've won with "In the silence of space" and I've lost to political cards that either wipe my fleets or just give my opponents free points. Just accept that it's part of the game and have fun. If you don't like the option, don't play with it. If you don't like the game, don't play it. We've had a player quit because TI isn't oriented enough towards combat, so we told him "It's TI, not A&A. If you don't wanna play a point game, we're ok with you not playing."
It is an added element of randomness in a game which indeed has a lot of random elements already, but something feels different in this case. It isn't up front-- some people's SOs are essentially just worth 3 VP now. We need to try to draw a line here between random elements that are fair and random elements that aren't. For example, even though the first person who is chosen as speaker is random, I think we can agree that the vanilla ISC, which caused the first player to win the vast majority of games, was going too far. With that in mind, I think a good rule of thumb is--
Randomness is fair under two conditions: (1) when players are able to prepare for the risk of negative outcomes by acting to improve their odds or eliminate the randomness all together somehow beforehand; and/or (2) when players are certain to have enough time to work together in a reasonable way and compensate for random outcomes that throw off the balance. An important corollary to number 2, in the spirit of promoting an all-around enjoyable experience, is that conditions requiring the group to instigate the effective elimination of a specific player due to random effects needs to be the result of an unlikely accumulation of several such positive random outcomes in their favor.
As an example of how this applies to several other random elements: It's easy to see from the beginning who has any advantage by virtue of the map layout and players will act accordingly throughout the entirety of the game; you can protect yourself from the randomness of Domain Counters by scanning or taking certain other precautions; you can put the odds in your favor with combat rolls by having a superior force. I don't think that the PO assisted SO fits here.
Don't get me wrong, I'd like to use POs, but I just haven't come up with a good 3rd Party rule that would make me comfortable with it yet.
