I know I started a thread about good flight simulators, but I wanted to ask about all combat flight simulators, including helicopters.

I'm having difficulty getting Longbow 2 to run on the XP PC so I was wondering if there was something as good/better for the newer PCs?

I'm also currently playing Jane's F-15, which is great, but flying the F-15 and only the F-15 gets a bit tedious.

Thanks in advance.
