Why waste your time. Wikipedia isn't a reliable source of information anyway, I think most people (should) understand it. I've seen articles that in the same page contradict themselves. Also, I'm beginning to think that let everyone call their game what they want, players will decide what they like or what they consider a roguelike. Even more so, we as developers should show a good example by creating games that are in fact roguelikes. Let's not stop at 7DRLs or smaller games but continue development and try to reach the roguelike standard. It's difficult, but it can be done.
