Over the last few weeks there seems to have been a major amount of game's having patches put into them These are usually to fix bugs or add compatability with other things ie Rumble function.
Warhawk: V1.2: Adds Rumble support, fixes a few glitches, allows for the Dropship to be used. This is the Omega Dawn pack which is £3.99, I'm currently trying to get a group of mates together to have a bash on this.
F1 CE: V1.1: Adds rumble, sorts out a few bits in the online stuff including adding ingame messaging. But still no promised PSP wing-mirror, boo, hiss!
R:FoM: 1.4!? Adds new map pack. Had skeletons running around for halloween, adds rumble and a new map pack. Which I'm yet to DL.
Others I know of are Heavenly Sword, Assassins Creed, Super Stardust HD. I'm expecting Ninja Gaiden: Sigma, CoD4 and a few others to get rumble added soon.
I should also have mentioned that Folding@home has been updated (now Ver 1.3) and now allows music to be played from the HDD at the same time as performing calculation for the protien folding project. It means I'm now doing more folding which is top.
