I'd love to go back to Delphi and play with it again as I did back in the day, but the price tag kills the mood pretty quickly.
It was a tiny software group in a large company, and paying Embarcadero whatever they wanted was just a matter of filling out paperwork. I imagine a lot of their current paying customers are in a similar situations.
You can do the same with Lazarus without any external libraries. I wrote a fairly polished production system for a seafood factory in Lazarus 15 years ago which is still in daily use.
Amazing what a single developer with the right tool can achieve, shame we cant get any young people interested in anything but apps.
It is basically open source and cross platform Delphi (there are a bunch of differences but from a high level perspective i think that it describes it fine for people who already know Delphi).
Also check this video i made a few years ago[0] making a simple puzzle game in Lazarus. You can skip to 11:30 if you don't care about downloading, compiling and configuring it and just want to see it in action.
