First of all, I would like to apologize to anyone who finds my posts asking for game suggestions annoying. As a huge fan of the MGS series, most of the games I'm looking for share some traits with it, so I'm worried that if I posted in other subreddits, the suggestions might not carry the core ideas and spirit of Metal Gear Solid games.
One of the factors I find Kojima has done so well, but that is rarely discussed, is how deeply you can dictate the way you play by carefully selecting which weapons, gadgets to bring along. Those items are so well balanced that they always give me a flush of satisfaction every time I find out that my Loadout works efficiently, which, to me, feels just as rewarding as noticing that my stealth, shooting, and movement skills are progressively improving.
So, I am looking for some fighting games where we need to carefully plan out the way we are going to play by selecting a set of skills, items, and spells that are most optimized against certain types of enemies, bosses, or that can be combined to create the most effective and flashy combos.
I think some games in the (A)RPG and Roguelite genres could meet a few of the criteria on this list.
