Oleg:
Expansion Packs and Mods are entirely different. Expansion Packs generally add new changes to the game code that allow for new features previously impossible in the game. Mods do not do this.

Hadrian:
My comment about UM1 not being very impressive was in relation to its title as the Ultimate Mod. Such a name gives high expectations. Also, on the download page for its initial release, it listed a lot of features that were in (not going to be in, but actually in) it, but almost none of them were. The second Version added a few of these features, but not all.
