Thanks for the warm welcome! I just haven't seen any thing that indicates they've leaned in either direction. Personally I saw that both girls have roughly the same amount of intimate interaction between the them and cloud. I think the only edge I saw to Tifa was the almost kiss which I'll admit does lean slightly more towards Cloti. There's also the fortune in which it states he will lost what he cherishes most, which to me was Aerith as I think that's the only thing/person he really loses after the fortune so that can also be a counter but that's more of a reach. I always felt nojima liked to mess with shippers. He'd like a tweet bout Tifa being a good wife, then make a statement about if it was Aerith, cloud wouldn't be fighting with her. Idk seems like a troll almost lol. This is all just opinion take it for what you will.
As for the whole satelite love thing, I'm assuming you are talking about how if no romance is canon, and aerith still dies, cloud will just live with Tifa despite her loving him. Yeah. That's just it. We have the option in the game to never do any of the dates with either girls which just makes cloud not interested in romance. Would you say this is cloud leading them on? If its player choice by the end, there is the option where he romances Tifa and aerith dies, or he sort of just lives with her, forever loving a dead woman, or he just lives with her platonically. I don't think that makes him a dick or leading her on. He doesn't have to reciprocate feelings for anyone, aerith included. Think bout the persona series. Once you get max level friendship, you have the option of romance or not. You can say no and romance someone else. Its really as simple as that in my eyes. FF7 is definitely more character driven so there is a difference but I think the same principle applies. The girl you don't chose takes the silent rejection, and accepts it. Also I believe its confirms cloud sleeps in a different bed and has his own room, maybe a translation error on that last part but pretty sure he sleeps separate and marlene always sleeps with tifa. The whole not answering the question when Tifa asks cloud if she loves him in the novel is part of the reason I don't like the extended content after the OG. It really muddies everything up and adds a lot of melodrama. The only part I liked bout the On The Way To Smile novel was the lifestream portions cuz they add to the lore of the remake. At the time of release though they were also pretty meh.
Lastly the weapons stuff is cuz cloud and the other still have a chance to get the final limit breaks and weapons, if aerith isn't able to party up or at least fight, she'll be the only one without the oppurtunity. I respect the opinion of not wanting to change the theme. I know a lot of OG fans rather keep it. I just think that so much has changed and introducing the defy fate stuff would feel slightly wasted and even mean if aerith didn't survive. That's just me though. I still think at least AC needs to be avoided so the defy fate tagline wasn't for nothing.
Couple things to go over here.
1. The devs have stated that they weren't fond of the affection system being in Rebirth, they obviously don't intend to make the next persona game.
2. Cloud and Tifa's romance isn't player choice, the scenes in Kalm, under Junon, and Gongaga are not optional, Trails of two pasts and 2k gil to a hero confirm that both Cloud and Tifa are
very romantically interested in each other. The lifestream sequence is a subtle love confession, part of it is him basically telling Tifa "everything I did in my life, was for you."
as others have stated, there are quotes from the writer himself that confirm that Cloud and Tifa were written in the context of "love, marriage and family", here:
“Episode:Tifa … first, there’s the premise that things aren’t going well between Tifa and Cloud, and that even without Geostigma and Sephiroth, it would still be the same. I don’t mean to get into my views on romantic love, marriage and family. (laughs) After ACC, maybe Denzel and Marlene can get them to. Perhaps things would have gone well with Aerith, but Aerith’s responsibility is big, I think. Oh, I remember. I also wanted to write about Cloud through Tifa. It certainly can be difficult to ascertain his feelings. (laughs)”
3. In CoT, it only confirms that Marlene slept with Tifa up until the night Barret left, so only about a week. The next time we have any reference to Marlenes sleeping arrangements is in Advent Children where she has her own bed. Marlene told Barret she would keep the family strong, so I doubt she continued to sleep with Tifa for much longer after that.
For "evidence" that they slept in the same bed, CoT claims that Tifa awaited Cloud's answer until morning (after she asked him whether or not he loved her). This would be entirely out of character for her if she didn't have a reason to be in the room with him all night, as Nomura states, quite specifically, that Tifa is not a clingy woman, and on the contrary that she is a strong woman. The only reasonable, in-character interpretation of this scene is that Tifa and Cloud share a bed.
For the bed in "Cloud's office" (Note that this is what it's actually called, it's never referred to as "Cloud's room"), I don't know why it's unreasonable to assume that they keep a spare bed in their house, Barret immediately springs to mind here when talking about somewhere for guests to stay. Cloud also runs a delivery service and works odd hours, it's also entirely reasonable to assume because of this that Cloud crashes in that room whenever he gets home late and doesn't want to wake Tifa, it's a very common thing to do in real life.
4. Yes, it does make Cloud an asshole. Accompying ultimanias and other sources state that Cloud and Tifa confirmed mutual feelings of romantic love through acts of intimacy that night under the highwind. So yes, Cloud confessing to Tifa in the lifestream, having sex with her, claiming she's with him in a different way than before, moving in with her, sleeping in the same bed as her, and raising children with her, only to go "sorry, all those feelings I had for you were completely undone because I spent a couple weeks with Aerith, I don't love you anymore" does, in fact, make Cloud come across as a massive prick, and 100% foots the bill for leading someone on.
EDIT:
5. Something else I would like to add is that Cid and Barret talk about Cloud and Tifa in the same context they talked about Cid and his wife, so take that as you will.
