I've been playing Cat Quest II with a girl I've been seeing. She's not exactly a gamer, but we've been playing some casual co op games and have had a lot of fun. We had finished Overcooked (great co op game, highly recommend it) and were looking for something new. She signed up for apple arcade, or whatever it's called, and saw Cat Quest on there and thought it looked cute.
At first I dismissed it for it's cutesy art style and simple look. And while it isn't the deepest game, it's perfect for us. It's a two player couch co op action RPG. So far the combat has just enough complexity to keep me interested without completely overwhelming her. Sometimes things get a little hectic and we lose track of which one we are, but it's still a lot of fun. She's getting good at drawing aggro one at a time with her range weapon, then leading them to me to bash the hell out of them. I also like the way they telegraph when an enemy will attack with a red circle, making it clear when you're supposed to dodge. And it's full of cat and dog puns, and cute hats to wear. Not something I'd play on my own, but it's great fun with a girlfriend, or maybe a child or someone younger. We do die rather frequently, so it's not as if it's without challenge. But the penalty for death is never that bad, as there are saves all over the place.
Does anyone have any other recommendations for couch co op games? We are looking at Knights and Bikes next.
