lol by the time 1.3.5 hits "new" gen consoles, the PS5 and XBwhatever will be out and they'll have to stop and then try to re-do all the code for those consoles.
This is why getting into consoles is a bad, bad thing. With PCs, you develop it once. I think in the last 20 years, we've gone through... what, maybe 2-3 major roadblocks? 16Bit->32Bit with Windows95 (and of course DOS->Windows95), Windows98->XP caused a few compatibility problems that were usually workable in some way, the Widescreen debacle where suddenly Widescreen became the new standard and most old games didn't support it properly, and then the 32Bit->64Bit jump. And, I suppose, some games didn't play nice with multi-core processors (but the fix was usually easy and done at the end user's machine, rather than the game's code needing patched).
But at the end of the day, Windows is still Windows. It will *probably* work, might need compatibility mode, or DOSBox with old windows install or something.
That's nothing like a new console coming out every 2-3 years that you have to re-develop the game for. I think any game that was made within the last 5 years will probably run on most modern computers with very little if any work needing done. Fact is, a lot of 10-15 year old games will work too with just a little tweaking.
But try popping that Playstation2 CD into your Playstation 4.... lol. Good luck with that.
