Yeah, FE7's plot has...absolutely nothing. Well, Lyn mode had...Sain <_<? Ok, not plot, but LYn mode definitely felt better WRITTEN than Eliwood/Hector Mode since characters could actually be used given no one actually dies; everyone just pulls a "crap! Injury that'll inconveniently last until the end of Chapter 10! I can't fight, but I can be here for plot scenes!" stunt instead. That's one of the problems with FE plot for characters and such; too many characters having permadeaths means that a lot of them can only get development through supports, and only in some supports. FE9/10 worked around this some with Optional Info Scenes, so you'll always get insight on some characters regardless of supports, just so long as that character is alive (and often enough, these scenes would reward you with something like an item)...but in any event...
Actually, replaying FE4, I think I figured out why the game gets plot hype. If you look at the core plot...its actually got some interesting ideas and stuff, and makes use of the generation system (just ignore the incest <_<;.) The problem is...well...the writing is so bad and the plot scenes are so split up, its so easy to get lost in all of it, so yeah. Just a case of "neat ideas, poor execution" etc. FE4's plot ends up sucky as a result, though still probably above FE7.
And yeah, FE7 is completely wasted as a prequel. I agree that Prequels should only exist if they are to expand upon previous events, clear up certain aspects, etc. Lufia 2, for example, taught us about Maxim and his adventures against the Sinistrals, so that worked; also, Lufia 1 has a bunch of random things tossed into its plot that Lufia 2 actually does play with (like Lufia 1 talks about a guy named Lexis helping Maxim...hey look whose a party member in Lufia 2!)
Or Crisis Core worked as a prequel for FF7. Its core plot was kind of useless for FF7, so that part was a Gaiden, but the random nuiances that tie in with FF7 worked, like showing how Zack met Cloud and Aerith, just what kind of relationship he and Sephiroth had, what Shinra was actually like on the inside, seeing it from a perspective that wasn't just "evil corporation" but rather, a "good guy" in a sense, etc.
FE7? Completely failed at this, as hinode stated.
ANYWAY...
MM9: Got to Wily 3, then decided to turn game off cause I know my brother was getting impatient and wanted to play on the Wii, so figured it'd be easier to let him do that. Anyway, game is...Mega Man 2.5 so far, is the best way to put it! ;_; to beat being his MM7 self instead of his MM5/6 self though.
