I started playing DL1 on a PS4 back in 2016 and transitioned to playing it exclusively on PC less than a year later.
My experience is that Techland has always provided great post-release support to include providing free DLC content drops for players, up to the present. The Following DLC was practically a whole new game, with new items and locations, and was provided for low cost. There's a bundle for both, (DL Enhanced Edition), which has been priced close to just the game alone on Steam, for the last several years.
Compare that to Ubisoft releasing Far Cry New Dawn after 5, when by all rights it should have been offered as a DLC to Far Cry 5. (And I'm a fan of New Dawn). It's hard to think of another game company that has provided similar post-release support for their games. I'm sure that DL2 will feature the same support from Techland because most DL1 fans will expect it.
I know they struggled to get DL2 out, with lots of delays and including controversies during development, but I hope that they're able to produce a better game than DL1, with DL2. We'll see. We only have two exact weeks to wait to find out!
