Aviation authorities can make realism concessions to older sims (20 years +), due to technical limitations of the machine. This means that an older, less advanced sim, can be still be rated at the same level as a more capable new sim. New sims have self diagnostic utilities which, can flag a problem in relation to motion fidelity.
A sim built in 1985 might not have the ability to self diagnose motion fidelity issues thereby, missing a motion fidelity problem for RTOs. If a few of your colleagues agree with your claim, then have a chat with the sim manager, see if he/she can get a simulator engineer to take a look at it for you,
