I used C++ Builder the last few years to create some unofficial game patches (most can be found at [6]) because it creates small executables (i used OpenWatcom before that, but i found creating the dialogs annoying and of course i didn't want to use Lazarus that makes 1MB+ executables just for a single dialog). Also i really like how fast the compiler is - i do not care it doesn't even support C++98 as i wouldn't use C++ normally anyway :-P. Like with Lazarus, i have a few classes[7] in it for utility stuff.
Recently i also made a mesh editor[8][9] with it. If you check my channel, i have a few "Making a game in XYZ" videos and i wanted to make a video where i "retrocode" a simple game using Direct3D on a Voodoo 2 under Windows 95, but i couldn't find any free mesh editing program that runs on Windows 95 (i tried some old versions of Blender and Wings3D but either nothing worked or was too slow - Voodoo 2 only supports 3D acceleration in fullscreen so the windowed mode programs have to be usable with OpenGL 1.1 using Microsoft's GDI-based software rendering OpenGL implementation). So i decided to write my own :-P. It mostly works, as shown in the video, but i haven't added a way to edit texture coordinates yet. I also tried to write a Quake-like editor[10], but lost interest. I did port (rewrote) the 3D widget stuff for my Lazarus tools though[11].
Ironically even though i spent basically my childhood with Delphi 2, i am not really using it much these days. I use Lazarus for most of my stuff (and TBH i wouldn't really rely on either C++ Builder or Delphi 2 to keep working in the future, although it works just fine under Wine[12] which i feel will be more likely to stay backwards compatible in the future than Windows itself). I did write an OpenGL viewport[13] and OpenGL 4.6 bindings unit for Delphi 2 though (which may work with later versions of Delphi), although the former is really almost a line-by-line conversion of my OpenGL viewport for C++ Builder[14] and the latter is just a unit generated with my Lazarus OpenGL unit binding generator[15] hand-converted to work with Delphi 2's Pascal dialect. I recently thought about writing a Nendo-like[16] modeller by porting my winged edge classes from Lazarus[17], but the day job doesn't leave me with much free time sadly :-P (and i have some games to play too :-P).
Funny enough, just before visiting Hacker News today i went to Embarcadero's site and thought about downloading the latest Delphi - but meh'd out when i was asked to register (i have an account, but i don't remember the details and i'm too lazy to go through the password recovery dance). Although TBH this is largely because every time i tried it the last few years i was really underwhelmed. I don't know, i never liked the post-Delphi 7 interface and i remember even at Delphi 7's time i thought the IDE was too bloated (granted, i was trying to run it on a Pentium MMX with 32MB of RAM...).
I wish there would be a version that had an affordable price (like the original Delphi 2 and C++ Builder, the base versions of both costing only $99.95 which lasted until Delphi 5 and C++ Builder 5 respectively and after that prices started hiking fast), was available in a box with nice manuals and CD/DVDs (or whatever, for that money i want to have something to touch :-P) and was free of any sort of DRM (i installed C++ Builder once when i got the CD off ebay years ago and since then i simply carry the installation folder around - which is kinda necessary since i've modified a few headers and lib files - if they had any sort of DRM i wouldn't be able to do that).
Basically i'd like a new Delphi 2 :-P. Although TBH this is more of a sentimental thought and in practice Lazarus does the job just fine, even if a bit clunky at times. Still, i'd buy a (proper, non-crippled, especially license-wise) $99.95 DRM-free Delphi (hell, even a digital-only version, as long as i got a nice .exe installer i could safekeep in my external hard drive) without much thought.
