I agree-If you are wanting to play solo, the Tiller games are pretty much a waste of time, as the AI is not very challenging, even for new players. However, if you want to play MP, they are pretty good. They are simple, quick and reasonably accurate. They also have a very wide variety of battles to choose from. Further, I use them to teach myself some of the history of a battle. For instance, I will frequently read an article or two about a battle I know little of. Then, I'll playing a scenario on the battle in the WDS series. This gives me a pretty good idea of how the battle was and could have been fought, and gives me a good jumping off point for more in depth research.
