Legends of Pegasus. Saw it on a Steam sale, thought I pick it up. Christ was that game boring. Not only did it need a real tutorial level (RTS games don't work with a Portal-style "make half the game a tutorial" approach), once I figured it out, I had no reason to play it. The plot was banal at best, the gameplay was designed for five-year-olds who are incapable of even the slightest micro-managing or multi-tasking, and the voice-acting was so far below sub-par that I actual dozed off during a cutscene.
