IL2 is great when you want to do the "real war" thing and fly a Yak or a 51 against scores of 190's, JU88s, or even some C205's and Zero's.
The view system may not be AH's, but you need to realize, if you played AOTP and AOE, same system there, same for most games. Its not that big of a deal.
Online its not as huge or developed in the way AH2 is, but if you go to the right servers you can have a lot more fun facing off against opponents and won't have to worry about 2k B17's taking out your FH's.
