all the pro pinball games have relatively similar system requirements. basically pick the table theme that interests you most. i think if i had to choose one i'd go with Big Race USA, but that's just a personal preference..

Way late here, but keep in mind that the GOG version of Timeshock runs through DOS Box, so your netbook has more work to do to run that one. That being the case, I'd go for Fantastic Journey, personally, but you should get similar performance out of FJ and BRUSA.
