Good games of the nonce

• Antagonist - An actor who plays the Dark Lord in a video game is forced to team up with an actual hero who wants to kill him. The game takes longer to download than it does to play, but it's worth it just for the humor.
  
• Robots Initate Work Sequence - A time management game similar to the base-building side of RTS games. The concept looked boring at first glance, but I couldn't stop playing.
  
• Solarmax 2 - A space strategy game like like Intergalactics or Konquest with very good ambiance.
  
• Sunken Spire - The core of the game is a routine series of themed levels, but if you step outside of the dungeon for a moment you'll see a richly developed game world and a pair of sidequests that are more interesting than the main story.
  
• Touhou: Wandering Souls - A fan-made action RPG with enough variety in monsters and their attacks that it does not get old, and the music is pleasant to listen to. For an action game, it is surprisingly relaxing.
