I always played Lawful Neutral mages in Baldur’s Gate 2 because which familiar you summoned depended on alignment, and LN got a snarky ferret companion.

I wish the feature was more fleshed out - familiars didn’t react to narrative events and you could run through his entire dialog tree in about two minutes. There are thousands of mods for BG2; surely one of them expands the familiar system?

And Divinity: Original Sin 2 had a squirrel riding a skeletal cat that was pretty awesome, though I think it was a preorder bonus.
