I've only played one game the whole way through with the DS3's rumble and that was MGS4 last year.
I like that the Dualshock 3 has had some changes so the analog sticks feel better than the Sixaxis, but I really don't care about rumble and find that it's more annoying than anything. I hardly feel like it's something worth using. It could be useful as a tactile repsonse for certain things though (rumble when using the menu's with the Wii-mote for example) and don't Baseball games use rumble as a way of selecting options for your next move without alerting the another player to your action?
