At the end of the gay...
Which end, may I ask?
Anyway, the games aren't directly comparable IMHO.TBP, being based on FS2, scores on overall gaming experience, but a hardcore realism freak would definitely enjoy B5:IFH way more, what with not having to be plagued by WW2 combat mode.
Also, it's very possible to dogfight successfully in IFH once you get used to it, as was said. It's completely different game in fundamental principles compared to FS2, and I like both in a very different way.
What was worst in IFH used to be an annoying bug that made the game run slower or faster, because the game didn't support dynamic CPU clock speeds. Thus, when the game started, it registered CPU's idle clocking speed as max speed, and when the CPU clocked up, it caused the game to run faster. I suppose it is, or it will be fixed, but I haven't had time to DL/install the latest IFH release(s).
