There are some small/ultra light aircraft simulators that get pretty close, being able to rotate the cockpit left right up and down. Still, can't really simulate directional acceleration/deceleration with possibly short bumps like landing gear contacting the ground and similar.

But definitely, any pilot will tell you that feeling all the forces is actually big part of good piloting, as you can feel what the airplane is experiencing & act accordingly. I took a ride in some small planes (a 4 person two motor plane and a glider) as well as an advanced small plane simulator and really, the simulator was good but not really comparable.

Not to mention extreme cases like air racing or aerial acrobatics where the forces are so extreme that they might prevent the pilot from having enough strength to execute control input or possibly even make them black out.
