You ignored his aside though: "For the most part". This is true, for the most part.
Just last summer sale alone, Bioshock 1, an almost decade old game brought in over half a million dollars revenue for that publisher. That agme has probably been doing that on every Steam sale for years. I doubt the console version is bringing much if any money these days.
between the end of 2012 & the summer of 2013 (a 6 months period), Gran Turismo 4 on Playstaion 2 sold 140k units, making around 1-2 million dollars.
We can do this all day, but he made a misinformed argument based on non-information, almost every single week PS1 & PS2 games go on sale on PSN, even if only GAFers buy those games when they're put on sale (just for the safe of argument), that's still a significant amount of money being made every week for 20 year old games.
Yeah, but if you buy a game for PC, you don't need to buy it again because the system is not retrocompatible. I can play The Witcher on my PC even if I've bought it 8 years ago. Opposite of console, when you need to buy it again if you want to re-playing it on the new system.
You're completely missing the point, yes the way software is sold on PC is more pro-consumer, but that's not what we're arguing here.
I am also aware that the sales of such titles, outside of promotional periods, are practically nil.
Promotional periods are almost every single week, even in dry months PS1 classics get a couple of discounts.
