I've been playing 7 Wonders for a while now and I really enjoy it. I've played the standard game and with Leaders, Cities and Wonder Pack extensions.
I'm amazed that the wonders are pretty balanced. I mean, I do better or worse with one or the other, but that depends on my skill and luck on that game.
So I assume a lot of effort was put into balancing them somehow.
I've also seen a pack that contains a lot of other wonders, for example the fan pack "Lost Wonders". Some of the wonders in this one seam pretty overpowered to me, or others seam weak. I don't have facts to prove this, it's just my opinion which can be biased by my skill level and style of play.
Is there a way to compute (mathematically) the fairness of a wonder? Or should I trust the creator (which may not be the creator of the game)?
I mean is there a way to transform a wonder into a number (or approximate number) or something that can be comparable so it can be compared to the others?
Let me offer an example.
Let's take the standard wonder Halicarnassus side B.
At a first glance being able to look 3 times (once for each stage of wonder) in the discarded pile would look pretty fair to me.
But the author added 3 extra victory points on it (2 for stage 1 and 1 for stage 2).
3 points don't seem to be that much, but I'm thinking there is a reason they were added, to keep the fairness compared to the others because otherwise it would be under-powered.
I'm asking this because I would like to check the fairness of a (non standard) wonder before including it in the game.
I'm not asking about sides being balanced. But about a way to compare 2 wonders based on a score or a range of scores based on a formula or algorithm, if any.
