Current strands of thought in my game design ideas

Some strands of interest are/have been:

• making part of a game in which the player is blind. (Neatly doing away with fully textured, 3D models!
• the use of music/sound in a more immersive way.
• A game that explores novel notions in networking. Serious games, augmented gaming?
• A game that is both entertaining and educational
  Looking at gameplay first and foremost. Using 2D line drawings to make false 3D. '2 and a half D' a la Starcraft.
• Making a game, or 3D world that encourages co-operation, and/or the free movement of skills and thoughts in such a way that poverty-stricken areas, or areas in need of basic skills to help with pressing issues, can utilize the time and skills of others.
