I think the concept of a realistic forklift simulator is awesome and would be a great tool for operators to gain some seat time with no risk and without the cost of having another person supervise them. I have had the chance to see some real aircrafts sims and they are good enough to train real airline pilots, but they are millons of dollars. I tried out a forklift simulator here in the state earlier this year, it did function and would provide some very basic knowledge to a person with zero forklift experience and would work on any desktop pc. But when it came right down to it, using the keyboard to maneuver the unit was completely unrealistic and even with the steering wheel and other controls they use, it still has the feel of a cheap video game. Until the technology and software get much better and more realistic, as well as cost effective, using a simulator will just be a novelty.
