Is is necessary to specialise wonder types in each city?

[skunkpuppy]

In Civ4 you should usually only build one type of wonder in each city (merchant, engineer, etc) to prevenr the GP pool from being muddied up with different wonder types. Is there a similar consideration in Civ5 from a GP generating perspective?

The GPs you get is no longer random, instead there's separate progress bars for each GP in each city, so it doesn't get "muddied up" anymore, you can pretty much control which GP you want. However, the +GPP you gain from wonders is pretty minimal though (like +1 or something), so I think you should instead concentrate on specialists and increasing the +GPP rate through buildings rather than get the +GPP from wonders (depending on the wonder of course).
