Here is something I always wanted with a modern turn based game and to make it feel fresh.
You play turn but record the entire game. In full and last combat sequence. Works better if the game is a 3d world. So play the game out in turn based. After a battle have an option to watch it as a movie in real-time, if 3d make it cinematic with various camera angles. At the end of the game you can then playback the entire game, cutting out the unneeded stuff, axe the dialog decision making, just show what the player(s) choose. Any type of inventory management is cut. Cut out all the fat. Just sit back and watch it as a movie, each play-through would be different, perhaps even an option to burn it to the DVD format so you can watch it on your TV.
