I've decided to just make a post that I can update whenever I want, feel free to post what you'd like in Rune Factory 5:
I know and accept that at least one bachelor/bachelorette has to look like a kid, heck often the protagonist looks like a young teen. I just don't want them to act like a young kid.
A very easy mode, for those that want to breeze through the game. And yes, an ultra hard mode for those that want a challenge.
No amnesia plot, it's getting harder to justify why and how it happened.
The main character to decide that they want to stay in town, nothing forces them to stay, it's just kinda awkward when the main character is made to stay in town and leave the life they might've had behind, like Raguna could've already been married. RF2 did this, sort of.
I'd like to see how the old mcs are doing, or at least hear about them. I know these games take place kinda close together with the one furthest down the timeline being RF4...I think but it might be nice to see Raguna or Micah again.
An inn or sleeping bags, especially if you have to go really far from home. I love RF4 but it's a little awkward having to go back home to sleep in the middle of invading the Sechs Empire. It'd feel a lot grander going home after the battle is over, you haven't seen your friends for a while, possibly a year depending on how slow you went, and everyone celebrates their friend's return.
I want the characters to be like the ones in RF4, dunno how they were in other games but I know that I personally loved the RF4 characters, and didn't like the RF3 characters as much. The characters in 3 were funny but so quirky it was hard to take them seriously and really care about their events. Heck, I didn't mind doing the harem with the other bachelorettes, the only heart I didn't crush was Raven cause I loved her character growth, and the only one I really remember was Raven because she had me emotionally invested. 4 had more realistic characters, obviously they aren't real but I could imagine that the love interests would be heartbroken. In 3 the only one I could see being hurt long term is Raven, the others would just cry in their rooms and be ok the next day.
Leon asking about our childhood friends in the game got me thinking. I want a childhood friend or family member to come by as part of the story, maybe even in the postgame. I can understand it with Tides of Destiny seeing as you're in the future, Final Frontier? Sure, Raguna may have written a letter offscreen explaining everything. But, surely the main characters had at least one friend or family member who'd be really worried when you don't return home for years and years after you go on a mission, and you don't ever write to say, "Hey, I'm fine." If you aren't heard from for a long time, someone should come looking for you.
Something else they could do is reward you for maxing out your friendship with characters. Like, before a boss fight, the MC could say, "This fight will be hard..." And two options will appear: "I'll be fine" "Remember who I'm fighting for." The former will let you continue as normal, the latter temporarily boosts your power depending on how many people have maxed out friendship with you. Maybe even an extra boost from your spouse and kid(s)
