I just remembered my frustration with the second-to-last regular mission of the first Rogue Squadron game on the N64. Holy shit was that mission hard. You couldn't really expect your wingmen to literally last longer than 5 minutes, so they certainly weren't any help. Hideously accurate Turbolasers, missile turrets and AT-ST's basically flooded the map, along with copious amounts of TIE Bombers. Fighters and Interceptors hounded you the entire time, on your back like a bad itch.
You're forced to make all these crazy and wild maneuvers just to survive, including the constant closing and re-opening of your S-Foils to get the speed you need. Good luck trying to fly this one with the TIE Interceptor or A-wing, unless your REALLY good at destroying things quickly while taking as little damage possible. The Y-wing and Falcon are just too slow; the ability to soak up damage becomes irrelevant very quickly with annoying TIE craft taking pot shots at you. The only options I'd consider viable are the either the X-wing or N1 (Naboo's Starfighter).
Thats not all. Even if you beat the odds, an Interceptor with very peculiar AI will start messing with you. He fires all four cannons at once shotgun style, and is freakishly accurate, even by AI standards. Its as if he's actively taunting you with the slow firing style, and I swear he took more damage than normal. He flew quite well. Even if you somehow managed to get behind him, he'd just instantly sharp turn out of the way and zip right back behind you. You're forced to do a hold bunch of unconventional maneuvers (read: spam the airbrake and twist wildly) just to evade him, let alone get a good angle for him for a precious few seconds of return fire.
Finally, once you've knocked out the remainder of his forces, that bastard Moff Seerdon (sp?) finally comes to town. Yes, the arrogant bastard thats been taunting you since Blockade on Chandrilla will descend to you in an armored Imperial Shuttle for a nice one on one. Said shuttle has a ludicrous amounts of HP- I hope you saved your torpedoes... And hope said torpedoes have the seeker upgrade... Even after you die several times trying to figure out how to dodge his missiles, you got a long fight ahead of you (unless you learn how to outwit him long enough to concentrate blaster fire on him, as I did).
It must've taken me weeks, if not months to beat this single mission, or at least thats what it felt like. It took me even longer than Defection on Corellia (that mission also took forever due to the broke-ass tow-cabling mechanic that was thankfully smoothed out in the sequels). And this was just on normal difficulty. I didn't even attempt this on Ace mode...
