I feel this. I have a lot of long games, but it's hard to sink a lot of time into them. I'll find one game I like and focus on that. At some point I'll hopefully finish the Trails saga.
I have dabbled in emulation of systems I didn't have, though I am doing this on a Steam Deck. On the TG-16, the games I wanted to try the most were Dragon Slayer VI: The Legend of Heroes (the precursor to the Trails series) and Tengai Makyo (Far East of Eden.) Far East of Eden has an interesting concept and a lot of nice art, but it's still not quite on the level of the great SNES or Genesis/SCD RPGs. On the other hand, I've gotten to play quite a few Saturn classics, like the Sakura Wars games, Albert Odyssey, Magic Knight Rayearth, and the second and third chapters of Shining Force III that were never officially localized. I've also gotten emulation for the Bally Astrocade, a 1970s-1980s-era console that was a technological marvel in its time, running on Steam Deck.
