4 is also really good but i feel like the side characters don't feel as fleshed out as they were when you played as them
perhaps because they're not the character you're playing as anymore but that doesn't mean they should feel like they're background characters
6 is good but drags, could trim a few hours down and it'd be a lot better
7 just isn't a good game though. people love that game but its too long and they reuse models way too often. they should have fixed that in the 3DS remake, but they didn't. I guess one of the most popular JRPGs in history didn't deserve more than 10 npc models
