You're free to make your own game just like Weird Worlds if you'd like. Just don't infringe on any of our copyrights and so forth. But it took me a year and a half to program this game, and I know that if I were to program it in a way that avoids any hard-coded numbers it'd take that much longer. It's easy to say "would, should, could" but it's much harder to actually "do". How long can you go on a project that you aren't being paid for?

FYI I've been making mods and games since the 1980's. I know the limitations of FPS engines too, and they're based on the core gameplay of FPS games (it just happens I make FPS games for a living). Player bounding boxes are always oriented a certain way, level sizes are limited to a cubic mile or whatever, there's probably a hard limit of 1024 entities that can exist in the world and so on. That's why mods for FPS games are generally FPS themselves, and don't fundamentally change the gameplay. (I made a vehicle-based mod for Quake and it was a pain in the neck...)
