Though it’s online, Path of Exile 1 has a fun necromancer path if you start as a Witch. I never finished the campaign but even then my max horde was like ~50-60 minions running around murdering everything for me.
Not exact sure if this fits your hardware requirements but there’s a lot of fun summoning abilities (especially with workshop mods) in Divinity: Original Sin 2.
