After even more play with no tech trading in civ4, I'm convinced it's a better system and adds more strategy to the game. In the old days you could trade for those dead end techs that had some usefulness, but not enough to deviate from beelines (like the liberalism beeline). But now I find myself having to make more strategic decisions. Like prioritizing military techs like Feudalism before liberalism (which means I often don't get it first). I feel there is more strategy this way. Sure there was some thought involved with trading techs, but that's hardly "real" strategy.
