You know why 7 was the WORST game in the series? Because they completely and utterly FAILED to make me give one iota of crap about any of the characters.
I lauged, literally, LAUGHED AND FELL OFF THE BED I WAS SITTING ON, at the "critical dramatic moment." I'm not sure that I could even take the game seriously after that point in the "story", if you want to call that jumbled ridiculous cast of goobs "characters" then be my guest....was more like a bad saturday morning cartoon. Good music, horrible graphics (Yeah, I'm sorry, I was and AM a PC gamer, and even for that era, FF7's graphics were TRASH compared to PC...jaggies SUCK.), decent FMVs, expected battle mechanics but nothing really engaging other than watching summon animations.
Also, there were technical issues with the run of discs at the start. FMVs locking up due to data stream errors, etc. At the time, I had to rent an additional copy to get past the second disc because one specific FMV locked up and would not play. Worked perfectly fine with a different disc. Moot point now, but it definitely chapped my arse that I had to go rent a game that had just been purchased.
Storywise....I think 8 is my personal favorite, 6 after that, then 10, 4, 5. But my god, yes, the Draw system in 8 is the most vile combat mechanic ever made, lol.
I say play em all, but FF7 is the most over-hyped piece of mediocrity ever. Honestly, they could do a LOT with a remake to improve it, then it might deserve some of the acclaim it's given, but I think Square is rightfully too afraid of the slavering hordes of rabid fanboys to even touch it for anything other than a straight port re-release.
