Just downloaded the sim Roller Coaster Tycoon from the inventory page of the Blackboard site. I must not have the patience needed for most of these sim games. I truly cannot sit in front of a computer for more than an hour at a time. I become much too bored. These sim games seem to take hours to get set up and running. I would rather sit outside and watch a squirrel in a tree or some deer eat corn in my field. These games are for people who actually want to sit at their computer for long periods of time. This sim does seem to be an interesting platform, but requires way too much time for me. It was a free download, so give it a try and tell me what you think.
