Man, I hate being someone who has to give a score that might pull down the average for FF6, but I have to remain consistant. Anyway, though, let's do this:
FF5- Okay, this is my favorite, though I can easily see why someone would prefer 6 or 4. This game fits in at the pinnacle of right difficulty- not too hard, but not yet too easy. It also had the best form of customization with your classes, letting you choose what best fit what you needed. Add in that it was the last actual challenging boss in an FF and the Battle on the Big Bridge, and you get my favorite FF game made. There's not too much bad to say, but it feels like it lacks that pull to completely shock me into the "best game ever" feeling. 9.2/10
FF6- It's a better game than 5 in many ways- more memorable scenes, characters, story, etc. It had an ape-shit insane villain and the opera house, which is, to date, my favorite scene in gaming. It also played well at the points where you needed to split your party. But this was also where some of the later series problems started coming in. While there were some tricky parts (floating continent being the first to come to mind), the overall difficulty was rather low, even going through the fight chain with Kefka. Certain combinations also led to the game being easier to break. (Genji Glove and Offering? Gem Box and Economizer?) Also, everyone being able to learn every spell kinda reduced the importance of the magic users, even if their magic was stronger. (Well, unless you esper-leveled a lot with Magic +2 espers equipped.) Of course, the only speed esper being Odin gives you that other choice... If these problems were addressed, it would be one of the, if not the, best game made. 9.1/10
