Clearly, we didn't mention the Civ V demo last night because Alec's opinion carries much more weight than your own. Why would you need to "try before you buy" when Alec has crafted the one true objective opinion* to guide your buying hand? No reason at all. Therefore, this Steam-requiring demo is of no interest to anyone. The launch trailer beneath the cut is equally uninteresting, for it can convey nothing which has not been conveyed in the definitive Wot I Think. Quake before our majesty.
*Quinns offers a secondary one true objective opinion over at Eurogamer.
