LIBERTY OPENER

With Liberty opener you actually get all the Liberty policies faster than with the Tradition opener.
Why? Because you have to "pay" more culture for one additional policy:
Required culture for worker with Tradition opener:..... 25+30+60+105+170
Required culture for worker without Tradition opener: 25+30+60+105
=> 170 more culture required which can't be compensated by the +3
per turn.
And it gets worse:
Because you picked the Tradition opener, you always have to pay more for the same amount of useful policies (in late game tradition opener is useless culture wise).
Think about it. You might have to pay 1500 more culture to get to the next policy in Rationalism, just because you picked the Tradition opener.
=> Definately not a good idea.
Conclusion: Don't take the Tradition opener when you don't plan to use anything else in Tradition and you don't need the extra border expansion.
