Betrayal is a little more stressful, and plays more like an adventure game than a mystery. It has a fun dice system inspired by table top games, and I've never played anything quite like it, so I'd recommend it if your looking for a fresh experience (which is the same reason I liked Strange Horticulture).
Not really. Eve Online is an anti-addiction since whatever you want to do, the game or your group wants you to do something different. As soon as you train for something, it will drop right out of the meta and you will have to switch. In Eve you have to continually fight for your fun like a raccoon in a dumpster with other racoons.
