>>36871178Why not use proper game to introduce someone to a wonderful world of Pokémon games?
FireRed/LeafGreen is the best first experience in my opinion.
Then he can go with Emerald, then Platinum, then HeartGold/SoulSilver. Then, maybe, X/Y, OmegaRuby/AlphaSapphire and Sun/Moon, but 3DS era of core games is optional and pretty skippable.
At the point of HeartGold/SoulSilver your brother would be already hooked by core series games, so you can start slowly introduce him to side games and spin-offs - Blue Rescue Team, Explorers of Sky, Trozei, Super Mystery Dungeon. Maybe even Ranger trilogy and Conquest.
Then maybe Pokémon Trading Card Game Online for PC, Magikarp Jump and Shufffle mobile for iOS/Android.
After that you can try experimenting with not-ordinary platforms like Nintendo 64, GameCube.
So there goes Puzzle League, Stadium 2, Colosseum, XD Gale of Darkness.
And lastly, you can try to introduce your brother to other games - Black/White, Black2/White2, UltraSun/UltraMoon, Gates to Infinity, GO, Let's GO... But I doubt that he don't wanna play this shit.
