DSGE models are designed be solved on your laptop in 0.0001 seconds. There are more complicated models, like Krussell-Smith, but it's not clear that they help explain macroeconomics better. Agent-based modelling isn't more popular because they assume that the agents are very, very stupid. Also, not only do they not produce closed-form solutions, they don't tend to lead to clear statements at all. Also also, the leading agent-based modeler, Cars Hommes, is infinitely better published than most economists, so he's not suffering too bad.
