The problem is that on the slower speeds things like unit production are slowed down at the same time as tech rate, so you're back at square one. I think this is one of the biggest flaws in the unmodded game and it's depressing to think that 99% of players are still playing this way, even in mods.
When you get more turns to play with things before they go obsolete, EVERY other part of the game is enhanced.
Yes, that's true.
By itself, speed isn't the only important factor.
The map you're playing on, your trade agreement, the difficulty level of the game, the leader... are also imortant factors that may speed-up (or not) the techs discovery and/or production, so the game. Beeing a spiritual leader on a northern (tundra) island isn't the same as beeing an industrial leader close to hills and rivers !
Many things are linked and it's not easy to balance.
Try a large random map (terra, archipelago, tectonic for example), with 11 to 13 civs, on Monarch (or more) difficulty. You will have an interesting challenge. This is how i test, play...and often loose.
