As someone who has played OG, Crisis Core and Reunion, Remake, and seen Advent Children, I feel like I can always just go on my phone and doomscroll while simultaneously playing the game. The game is very pretty for a classic-style remake of the OG and compilation. But the abridged structure that they went with to do a classic remake of the series (especially the original) is a bit rough imo. The game is free, so I don't think that's a huge detriment, but this is definitely not what I'd recommend to a newcomer who wants to experience the compilation for the first time. If EC was an actual 1:1 classic remake of the OG, then sure. But the rest of the compilation was told in cutscenes, many of them with lots of voice acting and also cinematics only doable in the style of CG cutscenes or a full movie. I guess as an OG fan I'm fine with this game; it does look super pretty and has amazing OST rearrangements after all. But the gameplay is honestly just so meh. The battles (at least early on from what I've played) are very easy to beat by doing almost nothing and no real strategy.

I have yet to play the exclusive Sephiroth side story. I intend to play it one day but not soon probably. To be quite honest I think it's pretty jarring that one of the most iconic gaming villains of all time has his entire backstory revealed and told to us for the first time in a free-to-play game that was originally exclusive to mobile (until the PC release three months later). If you really want FFVII players and the fans to like Sephiroth more than they already do, this is not the way I would have done it. Back when the Yuffie DLC for Remake dropped, I remember seeing people brainstorm a DLC episode for Sephiroth for Remake (or some other entry in the trilogy). And I think that would've been much more effective, and would've done pretty good numbers considering who we're talking about here.
