    > rose-coloured glasses of nostalgia?

    This can't possibly explain it all. I never played the remake, but I am playing original FF7 with modern mods (chiefly New Threat 2.0 [0], on top of 7th Heaven [1] and FFNx [2]; but also graphical mods like SYW which enhances textures with AI, a GUI mod called ESUI, among other things) and it's an awesome experience. Note that those mods are entirely free and made by passionate fans.

    I fully believe that a FF7 remake made by fans and for fans would be 10/10 even with a fraction of AAA production values.

    [0] https://forums.qhimm.com/index.php?topic=14938 (in general FF7 modding is mostly discussed in this forum; there's a "Documentation" link that discusses all changes but it's a full rebalance that changes item placement, the script of bosses, etc)

    [1] https://github.com/tsunamods-codes/7th-Heaven (it's like a package manager for mods, there's another called reunion and many but not all mods are available by both)

    [2] https://github.com/julianxhokaxhiu/FFNx (it's a modding framework for FF7 and FF8, some but not all mods depend on it)

  16. skyrim-community-shaders
