I would recommend going for games on a PC. If you don't have one, you can buy a mediocre laptop and just roll with it. It's cheaper and easier to get your hands on than a console. Despite the lack of exclusive titles, there's just a huge amount of games from history that you can access on platforms like Steam or GoG. Steam also has a lot of demos and you can refund almost any game you have less than 2 hrs played on without question.

Here are some of my suggestions...

If you loved Final Fantasy from the days of SNES, get Final Fantasy 10. This game is considered by many to be peak Final Fantasy. The HD Remaster is available on Switch, Playstation, or PC.

Cosmic Star Heroine is a game that's similar to Chrono Trigger in many ways.

Yakuza: Like a Dragon. Great turn based RPG with plenty of silliness. Decent story too.

If you want a VERY lore heavy series of games, check out the Legend of Heroes games. It starts with Trails into the Sky, followed by Trails to Azure, Trails of Cold Steel (this one is easiest to get into), and Trails into Reverie (coming soon). It is a very slow burn though. Part 1 of each subseries (that's an entire 25 hr game) tends to just be setup for the main story.

The Persona games (Persona 3 Portable, Persona 4 Golden, Persona 5 Royal) are a little more difficult and half the game is a simulation of a high school dating sim life while the other half is more standard RPG. But, great games overall.

I played Disgaea on the PS2 long enough to actually break a memory card. That was way back in 2006 or 2007. That save file had more than 2000 hours on it. I ended up jumping over to Disgaea 2 after that

Metal Gear Rising was this for me for many years. I finally got to it in 2022
