Steam's Daily Deal is Eufloria. Interesting-looking game, but I probably won't get it.
It's VERY slow to get a game started, but once the action starts there's a LOT of micromanagement to be done. Essentially you're simply waiting patiently for the first 20 minutes or so for your forces to build (maybe have some reading material nearby), then when you're ready to attack, suddenly it becomes this huge click-fest as you're giving directions to hundreds of little units at your disposal.
Visuals are pretty artistic and nice to look at, but if you're really playing the game then you're probably zoomed out anyway since it's so much easier to manage the battles when you have a clear view of the entire battlefield.
