firered/leafgreen is my favorite, i love the gba games. if you're ok with cutscenes (ultra) sun/moon is also good

Pokemon rubin omega

I recomend black 2 since its the best gen story wise, but i highly suggest blaze black 2 redux for a better experience plus an expanded storyline

Either a GBA/DS Mystery Dungeon Entry or the GB/GBC TCG games

try pokemon black 2

Ive only ever played omega ruby, but I really like it! one of your starters can be mudkip so i think its good. :3

Pokemon moon

pokémon soul silver is a good game
