Forza for XBox if you're really into racing. Imo Gears Of War and Halo are not really that much of games. Extremely overrated if you ask me.

For Playstation basically almost every exclusive they have. They are just generally phenomenal for me.

For Switch you really need to be into RPGs to keep it. If I had money to, I would easily buy a Switch just to play BOTW and Pokémon
