I replay Colonization regularly,and the only thing I hate about it are bugs with wagon train routes that stop me from efficiently automating them, and a hard limit on 256 citizens. That's really low for a big developed economy with strong army.

Completely agree. For me the upbeat music really made the atmosphere of the original Colonization, and the later remake (based on Civ 4?) with its more downbeat soundtrack was much less enjoyable.
