I swear they made Supply Lines easier in the PC version of San Andreas. On the PS2 it took me hours to complete the mission, whereas on the PC I finished it on my first or second attempt without any trouble despite still sucking and failing at controlling the damn plane. Thankfully GTA IV did away with everything related to RC planes.

Shenmue II had this one really annoying portion where all you did was cross narrow planks using QTEs (with the D-pad, no less... I was playing on the Xbox, which made it even harder.), and if you missed one input you were dead. This went on for ten floors or so. Now, you can save whenever you want in Shenmue II (including between the aforementioned planks), but take a wild guess if I happened to know that when playing the game for the first time. So yeah, I ended up having to attempt that part at least twenty or thirty times, each time starting from the bottom floor. This, of course, included several tries where I fucked up at the top floor and the very last goddamn plank. Naturally, when you finally reach the end of the plank crossing bullshit, you get a cutscene where Ren greets you and informs you that he used the elevator to get up to the top floor. I guess that's supposed to be funny, but somehow I wasn't amused. Anyway, how come there was no elevator when I looked around the building earlier?

Yes, the main reason I found this so frustrating was the fact that I was a moron and didn't notice the save icon in the menu beforehand, but the whole part is just so incredibly tedious and difficult anyway that it's easily my least favorite moment between both of the Shenmue games.
