I seem to remember one of my cousins having one and I played it with them years ago on a big screen TV. I can't remember what game it was, and I was barely cognizant of different systems at that point. (I think I was just a bit past 5.)
Anyway, fast forward around the early 2000s when the internet and my passion for gaming was really taking off. I remember it being referenced in some online articles I was reading. It began to fascinate me.
Then, when the Wii came out I decided to try out Bomberman '93 on the Virtual Console. I was not disappointed. 5-player battle mode is as fun as it sounds!
Then, around 2009 or so, once I finally got fed up with the Virtual Console for not putting out the games I wanted, I started getting into retro gaming. I started with a Retro Duo (NES/SNES famiclone), picked up a cheap refurbished PS2 to play PS1 games on, then a Genesis, then I ditched the Retro Duo and got a real SNES and NES, then a Sega Saturn, and a Dreamcast.
Then just about this time last year, I was snooping around looking at prices for TG16 stuff, but wound up finding a PC Engine that was much cheaper... and boom goes the dynamite.
Guess I told you a bit further in than just my first encounter, but hey, I'm a writer. It happens.
