Ten Ton Hammer: "The expansion is pretty awesome, I like it, but there are some faults and most of it boils down to a lack of content. The campaign is short, there are only a handful of new units, and most of the other changes came with a patch before the expansion even launched. To top it off, some stuff is kind of just not really interesting like the XP for killing units in multiplayer unless that’s your cup of tea.
However, it’s still StarCraft II and StarCraft II is an impressive game. This doesn’t change that or alter it much, since there isn’t a lot there to alter or change it with. To that extent, I’m going to rate the expansion a bit lower than the original, but still suggest that you play it if you love StarCraft II."
