According to Katsuro Hashino-San, the FemC is not worth it and gave a confounding reason for why one was OK to work in P3 Portable, but wouldn't work in P4. I disagree, (and so does the interviewer) here's why.

One dominant colour representing and informing the themes of the game is shared across the majority of Persona games, and given that Green is the one eluded to in an official image (shown in video) here are six potential ways that the colour can be used in Persona 6.

My Unscripted opinions on the 10 games that made Atlus's poll as most desirable to be remade.

This is a video on Persona 3 Portable: Velvet Blue.

Gameplay footage (both FES and Reload) from Johneawesome.

With Persona 3 Reload mere weeks away I figured that now was a good time to speculate on what it could mean for more potential "Reloads" and which MegaTen Game I'd like to see get this treatment the most.

School Clubs are one of my favourite features in Modern Persona, and one strangely absent in P5. Here is a video dedicated to six clubs that I'd like to see in Persona 6 if/when this feature returns in that game.

Anime:
* Hanebado
* Iwa-Kakeru!
Art Footage from
* North of the Border
* Serpa Design

An admittedly gimmicky animal mascot per Numbered Persona game that can still inform at least a bit of the game's themes has become a staple of Persona for better or worse and with Persona 6 being inevitable that leads to the question of what animal the mascot will be? Here are six possibilities.

The Second Part in my Spin.Moe double-feature. I'll be uploading a List of 6 that I've long wanted to do next week, and hopefully at least one more video before the end of December.

I recorded this video in preparation for the Holiday season, but expecting that I'd have at least one of my delayed videos out by now. Needing to buy more time, and still hoping to get some views, here is my two part Spin.Moe video, the second will be released next week, and after that, it should be a video a week for the rest of December.

Sense I've been delayed from working on the videos that I want to work on, I decided that I should upload my other Spin.Moe Anime video that I recorded back-to-back with my previous one. It's the same as that one as well, just my unscripted thoughts on Anime that I've completed as they are spun from Spin.Moe.

Unless I've been massively delayed again, the next video should be out by next Tuesday.

Persona 6 is inevitable, and one minor gimmick that I hope to return are the Shadow Monikers that Demons are known by when Shadows as opposed to Personas. As such these are 6 Potential Shadow Monikers for upcoming Shadows in Persona 6.

The 30th Anniversary is Over here's a video on that.

This is the fixed Audio version of a previous video from earlier this year. I've uploaded this Fixed Audio Version because my next video will be a wrap-up of sorts for the 30th Anniversary and this video is a part of that Playlist.

Persona 3 Reload and Persona 5 Tactica were announced and so here are my initial thoughts and feelings.

Today I used Spin.moe to spin for Anime that I've already completed and gave my raw, unedited opinions on as they came up. Here is an unscripted List of Six of me doing that. My next video, the one that I've been editing lately should be out either by the end of this week or early next week.

My Pride Month Special. Sorry that it took so long to finally get out, but here it is. This is why you should watch Simoun if you want to celebrate Pride Month by watching an unapologetic Queer Anime.

In a return to Unscripted/semi-scripted content, I did just that as an experiment for things that I'd like to see in Persona 6

6 Demons from my favourite game in the series that have yet to make an appearance in Persona. This video has been a long time coming, sorry for the delay, but please enjoy.

Persona 5: Phantom X was just announced and so I put together my thoughts on the game, and made a basic argument why I am cautiously optimistic about it.

This was a video to quickly test my screen capture software and so I figured that I would make a video trying to sell my audience on one of the most underrated SMT games: Raidou Kuzunoha Versus King Abaddon!

This video should explain why I am not excited for SMT's 30th Anniversary
