I can't believe that I made an account just to reply to like, two threads. Hahaha.
*I agree with everyone that said that the series became too much fanservice happy in recent games. It reminds me of my extreme Weaaboo days that I had until 2011-2012, and I would REALLY like to forget about that. (I'm probably going to unironically enjoy the skinship thing though. The thought of treating your human friends the same way you treat your supernatural pets from an alternative universe is just too funny.)
*Talking about fanservice, I really hope that making Original Character Do Not Steal of the three most popular characters from the previous game isn't going to be a thing. It just felt really lazy, you know?
*Please don't add the marriage system again (Unless it's a Genealogy remake). the marriage system in Fates actually sounds even lazier then the clone characters. How do you even manage to do that? Hahaha.
*Also, Please please PLEASE don't put plot points and entire stories behind DLCs. There's no reason why Invisible Kingdom couldn't be an extra story after beating the main story of the version you choose and there's no reason why Invisible History couldn't be Gaiden chapters / Paralogues / Whatever they call it this time. Not everyone have a visa to buy them, you know.
*This is probably just me, but I really wish the Avatar was optional. I usually really like self inserts but in Fire Emblem they just feel really... forced, You know? All the characters agree with your Avatar's actions, they all love your Avatar (And probably fall in love with them) and if they don't love the Avatar they're probably evil. The Avatar also can't make bad decisions because they're supposed to be you and it's just.. like... no. I didn't read Fates spoilers in a long time but I think Black Kingdom and White Kingdom suffered the most from this. If Black Kingdom was about Xander, White Kingdom about Ryoma and only Invisible Kingdom being about the Avatar maybe it could've been better.
*The grinding in Gaiden is the only thing that stops me from unironically loving it. It's a good thing that grinding in later games that have world maps isn't as annoying. Hahaha.
Anyway, right now that's really about it. Sorry for writing too much. (Especially about the Avatar)
