Possibly.. although I'm not an expert. They kindof look old or something, and I'm guessing they shouldn't be.
I always feel as if there's a certain quality about these ISI titles, like the tracks are too clean looking and too boring. Everything's somehow a bit too perfect- a white-toothed plastic smile Barbie land for sim racers. Atleast Eric's tracks have a bit of imagination and RL grunginess, even if they are a bit broken in places.
disclaimer - i've only ever played ISI demos. Can't comment on full games.
