I have had a 60GB backwards compatible PS3 for going on 3 years now. I've used it off and on during that time for Netflix and as a Blu-ray player, but I've never really been able to get into it as an actual gaming system. In the entire time I've owned it, I've only purchased three PS3 games. The two I've had for a while now are GTA 4 and Valkyria Chronicles. I never got very far into either.
One of the main reasons I think I've never been somewhat annoyed with gaming on the PS3 is the sensitivity on L2 and R2. I just keep registering presses on them without even trying! I got a Dual Shock 3 to supplant my original Sixaxis controller quite a while ago (no regrets there) but I have the same trouble with both. I suppose I could just hold my fingers away from the buttons all the time, but it's a lot more comfortable being able to have my fingers pressing down on them just slightly.
The reason I'm bringing this up is because I've noticed several good deals on Amazon.com lately for PS3 games. I'd like to start getting some of these titles before they become harder to find. I picked up 3D Dot Game Heroes recently and that gave me an excuse to plug in my PS3 again for the first time in 4-5 months. I'm thoroughly enjoying it, but I keep dying because I keep pressing L2/R2 by accident and selecting the wrong secondary weapon!
So I guess my question is this: Is there some obscure setting on the PS3 that I'm not aware of that reduces the sensitivity on those buttons, or some 3rd party controller that doesn't have this much of an issue?
Also, feel free to just tell me to man up and learn how to use the controller properly if you like.
