Levels in the wonders

[Eiskalt]

What about the idea to have levels in each wonder like in Forge of Empires. Every level has more boni from the wonder. Example:

Pyramid Level 1: +10 % combatstrenght on deserttiles for all landunits.
Pyramid Level 2: +20 % combatstrenght on deserttiles for all landunits.
Pyramid Level 3: +30 % combatstrenght on deserttiles for all landunits.
etc.

But you have to pay for it. Either in productioncosts (time) or gold etc. . Each level has more costs.

What do you think about it?

I like it, also i think wonders should become obsolete after some time in the game. I don't think that is realistic to expect that whatever bonus the pyramids were giving in 2000 B.C is still valid anymore in 2000 A.D, 4000 years later. Instead, the pyramids and other ancient wonders, they should be giving a huge tourism benefit in the late game.
