Started playing Star Trucker - it’s pretty interesting, reminds me a lot of the cargo hauling loop in Star Citizen. The differece is that this doesn’t crash anywhere near as much, runs on my Steam Deck, and boots a lot quicker too.
FFXIV can be played with just a mouse. Free to level 60 (mmo)RPG with good story telling. But using the mouse in your left hand might feel strange tbf.
