Here are the Steam Game Deals for 7/23. Jericho and Altitude are both 50% Off. Also Civilization V is the Steam Weekend Deal at 66% off.
Altitude is this awesome indie multiplayer dogfighting game. It kind of reminds me of subspace or something. There’s a Steam free weekend going on for the game so definitely at least give the game a try. There’s actually a pretty good sized community of players for it. It’s on sale for $4.99 / £3.49 / 4,49€.
