Tried it initially mainly because WB connex generally were very poor. Also because I had just finished a series of sorties where I had unloaded the majority of a Spit's 20mm into other fighters from Dead 6 o'clock and 200 yards and watched them fly off after the guns went dry. That started to get too me after a while.
Where is it going? Easy. It's "going where the money is". Has to, or else it won't survive. Where's the money? Right now the response to another game shows that a more combined arms approach is appealing to a lot of people. This could change though.
For me, the nice thing is that this game grows step by step. New items are added to a system that already works. (Yes, there are a few things that aren't perfect. Always are in any game. However, this progression is working far better than the other alternative which remains basically unplayable and far from what was intended.)
In short, I'm betting 2 years from now will see a detailed "combined arms" opportunity that actually works on normal computers.
Or maybe not.

But I have faith in HTC. They keep improving it, so I'm following along and enjoying myself. As long as that continues, I'm happy.
