Since nobody won the Unreal Tournament on Lewis structure on Wednesday we tried again on the Friday class. Mike Aquino completed the quiz within 2 minutes and another student shortly after. That tells me that there was probably some practicing going on, which is the point of these exercises, after all. Many of the other students continued playing after the race was over and I think that is a positive indicator. Every time you go through the map you should be able more and more to recognize correct and incorrect Lewis structures instinctively.
The game design here has no weapons and uses the light (15 Meg) educational version of Unreal Tournament. It played well on all laptops.
