Why wouldn't the PC count? I've never understood how the PC isn't classed as a valid gaming platform... I find that attitude rather elitist, which is ironic considering PC gamers are known for being elitists.
On Topic: The 1st games I played were on the Master System. Alex Kidd in Miracle World, and Sonic the Hedgehog 8 bit edition. 2 hard as hell games, but so fun.
I eventually got my own console one magical Christmas, the Mega Drive. On this I enjoyed so many great games over the years, the Sonic series, Ristar, Dynamite Headdy, Judge Dredd, Streets of Rage 2, Columns, Soleil, man I loved that thing.
Eventually as the years went on, the 3D age started, and I got a Playstation. I still remember to this day how awesome it felt playing Crash Bandicoot 2 for the 1st time. Nothing will ever beat that experience. I also played my 1st JRPG on that console, Final Fantasy VIII. Maybe it's nostalgia blinding me, but it's still my favourite of the series to this day.
