The air system doesn't seem to bad to me. I don't go to deep into the nuts and bolts of the air system but people can if they want to, and the results don't seem awful when the computer runs it. Thing is, is that there are plenty of lighter wargames, games with less detail, games that take less time but not to many people making the highly detailed monster games. What I always appreciated about WITE/WITW is that there really not that hard to play, you can go into highly detailed play if you want to, taking hours for your turns but it's not required. I've had WITE for quite a few years now, and maybe put in about 500 hours into it and I've never played the grand campaign......yet, hope to one day, it's a bridge to far for me right now. I've had plenty of fun playing the smaller scenarios, especially the " Road to" scenarios. Of course YMMV.
I didn't get WITE on release, not for a few years, there wasn't that many smaller scenarios in release to justify the premium price of the game for me. I hope there are a bunch of "Road to" scenarios , but if not, I'll wait.

I don't buy all the wargames I want, I just buy more than I need.
