firstparty (adj.) Of products, created or published by the company responsible for the platform on which it is released (or its internal developers), as opposed to thirdparty.

Over the last three decades, Sony has published some of the best games ever made on their platforms. Also some of the worst, some of the weirdest, and some of the most unexpected. This is the first part in an indefinitelylongrunning series where I'm going to be looking at every game they've ever published, starting with the 29 games bearing their label that released in 1994 and 1995.*

* according to Western release dates unless Japan exclusive (basically I haven't missed anything, I'll just get to it another time)
