I wasn't even born during the 4th generation, but I still managed to grow up with the SNES, and for the longest time didn't even know the TG-16/PCE was even a thing...
I discovered the system through the Wii's Virtual Console and my first game played was Dracula X Rondo of Blood and I was immediately hooked! I wanted to know everything about the system, started downloading games left and right for it, both for the Wii and for emulators, I don't remember which where my 2nd and 3rd games, but I believe they were Ninja Spirit (because of the 16 bit gems video) and maybe Bonk's Adventure? Or was it Super Star Soldier? I don't remember, I was playing a big bunch of TG-16 games at the time (and still am)
Unfortunately the prices are a little prohibitive, and I'm a broke college student, so I don't own anything for the system yet (unless you count Virtual Console games as 'owning' them, in which case I 'own' plenty)
