This is a good idea. Once you learn to play like this you can add in the occasional wonder. But going wonder-crazy is a good way to get killed at higher levels unless you are industrious + have stone/marble + have a plan in mind or are going for a strat like Obsolete's.
Focus on horizontal and vertical expansion. For horizontal you want workers and settlers early and then lots of military later. For vertical you want food surplus + hereditary rule + health resources/buildings.
Focus on economy. This means pottery > currency > col > cs > liberalism > printing press > democracy > astronomy
OP: I disagree. Any absolute statement like "don't build any wonders" is dangerous, as even one counterexample disproves it.
Hermit: I agree, sort of. What's the trade-off? You can't think of it as "I can have several more units if I give up this wonder" because there is also the penalty of having another civ get that wonder instead, and that can be painful (which is why I'll blow a GE on stuff like Sistine Chapel if I'm already getting culturally pushed).
I've moved almost full-time into Emperor, on various maps, normal speed. In my playing style, some world wonders are must-haves/must-denies, some I only build with resource bonus or with GE or if I have such a huge lead and high production that I can build it fairly safely without fear of it getting poached.
Tier 1 must-haves/must-deny-to-enemies:
A. Gr Wall, Gr Library, Statue of Liberty, Mausoleum (partly for denial purposes as AIs burn their GPs for golden ages quite often, though this becomes Tier 2 if I miss the Music free GA), Pentagon, Taj Mahal, 3 Gorges Dam, and all late-game happy wonders (Broadway etc.) so you are not dependent on someone else to trade you your happiness.
B. If I plan to have a state religion (especially with AP hammer bonus), I also go for Spiral and Sankore regardless of cost.
C. Also Space Elevator if I plan to go for/deny Space Race.
Tier 2 build it if you have the resource bonus or can build it safely: everything else (including Pyramids, Parthenon).
In my current game I wasn't going to build many wonders, but I started off next to marble... I didn't bother going for Tier-2 stone wonders except Sankore and Spiral, as I also had Sistine and someone made AP and I converted to that religion and religious-building-spammed for hammers/gold/beakers/culture.
In other games where I had no marble/stone/ivory/gold, I built just Gr Library and that was it for a looong time. (Missed out on the other must-haves like Gr Wall in that game. Won anyway. So even a must-have isn't a MUST have.)
In summary:
- Some wonders are better than others.
- Be opportunistic when building wonders, especially if you have the resources for it. Don't decide before the game even starts that you won't build any wonders.
