Westy, your most recent post you forgot to mention the infantry portion. None of the other games you mentioned has infantry. Now, if you're just talking in terms of goals, then yes, you're right. The methods of achieving the goals are different though. In AH you can use nothing but fighters and a goon and capture territory. You can also use ground vehicles if you so desire. In WWIIOL, you have to use infantry to take the base, but usually, you need some support from at least ground vehicles. Of course, I haven't played since they went pay to play, so I don't know if this is still the case.
Your other points are very much valid.
Swulfe, you're right, every release does get them closer to what was originally promised. However, doesn't that make it better than the state in which it was originally released?
