sorry I was being rude, I was in a bad mood.
Yes, all those games have more interaction online than just online global scores, though not all are traditional live multiplayer. Fantasic contraptions allows you to share levels and designs you've created, and to rate/play other people's. Aurora feint has this clever ghost interaction, where it simulates another player or something like that.
Most games that would benefit from online multiplayer will have it. The iPhone is meant to be online.
