Normally I wouldn't post this here, but I totally had to, because Nitro+Chiral's sweet pool has one of the neater methods of manifesting decision points I've seen in any game. It's essentially the same as the red/green triggers in Chaos;Head, but soooo much more visually jazzy.
Short example video is here. Do you guys know of any other games that dress decision points up like this? I'm curious.
