I third the recommendation for
Dragon Quest- I only played the demo recently, but I just ordered it from Amazon. The demo, by the way, is EXTREMELY long- I got around 60 hrs of gameplay out of it. You should definitely check it out & download the demo if you're interested.
Other recs:
Fire Emblem: Three Houses - this game absolutely rules. if you have even a passing interest in FE, you should check this out.
Octopath Traveler - a game that was super hyped when it came out & but now... it's not quite hidden yet, but it's a gem. if you don't mind 90s pixel-style JRPG graphics, this is a great game. Also has a demo on the eShop totaling up to about 5hrs of gameplay.
Okami HD- I haven't beaten this one yet, but it's got stunning graphics & fun gameplay. Incredible for a Wii port.
Phoenix Wright: Ace Attorney Trilogy Remastered - I had no idea what to expect from this title & I loved this game. Great for people who like logic puzzles & cute anime characters. Great character interaction & dialogue. + It's very fun to yell "OBJECTION" at Edgeworth lol.
ARMS - specifically chosen b/c you like Splatoon. ARMS has really pretty graphics and addictive online gameplay like Splatoon. The similar art style drew me in at first. Not much of a single-player campaign, but Splatoon players are accustomed to that.
I hope one of these is what you were looking for! I'm always expanding my games library
