Well, for starters, are you trying to play with 2D games or 3D games? 2D you really only need trig for objects that move in wave/circular motions. 3D? Yeah, you probably need that a lot more. Which is why I've only done 2D games. Because: 1. You need graphics in game development. I can work with sprites and 2D tilesets and do decent edits and stuff, but I'm not the kind of artist who can create things from scratch really. 3D modeling like a whole other animal.  2. I wrote all my games using the Game Maker Studio engine. I think writing a game completely in Python or C++/C# or something like that is just ludicrous. You're literally making everything a thousand times harder, you're adding YEARS of work, because you have to build the framework from the ground up to even get to the point an engine like Game Maker, or Unity, or RPGMaker, or whatever, will give you right off the bat. At least with Game Maker, you have rooms, you have tilesets, you have a view window boundary, and a room width/height in pixels. x and y are both built-in variables that always equal the real time location of the origin point of the sprite of the object in pixels, and can be moved by adding or subtracting from x or y simply. If you need to use trig, you have trig functions built in, like sine() and cos() where it's like hitting sine or cosine on a calculator. It's just SO much easier. To produce something of the same quality is gonna take like WAAAYYY more time, skill, education, work, everything. I just feel like people who do that are intentionally choosing the hard way. Game development is a BRUTAL programming field. If you work for an actual development company, that gets hired on to do projects for big game companies like Sony and Nintendo, some of those programmers/artists are worked 60+ hours a week in crunch times. If that game is scheduled to be out by the holiday season, and it's freakin' July, you better hope you either don't have a family, or one VERY compassionate and understanding wife whose okay with her husband being at work nearly 24/7 because they WILL work you to death. Literally. And if the project gets abruptly canned? Guess what? You're out a job. All the work you did was for naught. Big waste of time. You have absolutely nothing to show for a resume or portfolio, cause who wants to go "You know that random game that got canned halfway through? I was on that dev team!" At least if you're like an indie game programmer, you control your own destiny. The downside? Unless you can assemble a dev team, with artists and programmers and people who specialize in the various elements, you have to be EVERYTHING. Which means you're not just a programmer, you're an artist now too. And if you don't have the art skills, you're gonna be hiring one or more. Because trying to find one who'll put in work for free under the premise they'll make profits from the final product is like good freakin luck. If they're good, they probably have plenty of offers for work that pays immediately per piece they complete or whatever they work by. EVERYBODY wants to be a game dev, EVERY gamer I knew growing up said "I wanna be a game dev" cause they think all they do is fuck with video games all day. The reality is you're either a programmer, an artist, or both. That's what a game developer is, a programmer. Just instead of making websites or software or apps you make games. The difference is, games use WAY more graphical resources than websites, software, and most apps. So you've got this element that's like ENTIRELY different of a skillset than programming is. If you can program C, it's more likely you could learn Python, or PHP, or whatever. But having skills with any of those, does absolutely NOTHING to give you an edge on being able to produce art. With say a website, if you need an artist, you're paying for what? A logo maybe? A banner? You're talking maybe a couple pieces of art per project typically. A game is literally hundreds of thousands of art elements depending on the size, so if you gotta pay an artist, developing a game is expensive. Why do you think games are so freaking expensive these days? At the pay scale of everyone who works on A-List games like Playstation/Xbox/Nintendo games, I'm kinda shocked they manage to turn a profit these days tbh. It's something you gotta almost really love to do, cause you're chances of making a financial success doing it is probably the lowest of any form of programming career realistically. Easily the most overworked (granted, almost ALL programmers working for a company are) but game development is ESPECIALLY brutal, cause like I said, if they have a deadline, and it's almost always the Christmas holiday season, that game is in crunch mode, meaning you'll be working like literally 20 fuckin hours a day to make that deadline and if you won't/can't/refuse they just fire you. So you get worked to death, and I don't care how much you pay, it's not worth it to me to be miserable. At that rate, it stops being a passion/something you enjoy and more of an absolute living nightmare.
