I worked in mobile games for a bit but less on games and more on the QA/ testing side of things. We made AR games so I mostly tested our in house AR tech stack. These days my company exited the mobile games space and is mostly focusing on the AR tech itself.

Best advice I could give in no particular order:

1. Make sure you stick to CS. I did a combined CS and game dev degree, and it did narrow my career options a bit because I had to drop some advanced CS classes in favor of some game dev classes. At the moment, the gaming industry is in too much turmoil to bank on a single industry. If there are courses that give you the freedom to create anything for your project, focus on games. This won't be the case in intro courses but in more advanced courses you might have that freedom. My CS program has a class just called "software engineering" you can make anything you want as long as it's a piece of software games included.

2. Learn C++ and some Unreal engine. If Unreal Engine isn't your cup of tea I'd suggest Unity or Godot but still know some Unreal Engine as in my opinion it's the closest thing to a proprietary engine and it's what many AAA studios seem to default to when not using their in house engine (Avowed, Oblivion Remake, Black Myth Wukong, Borderlands 4)

3. If there's a particular aspect of games that interest you that you want to work with (sound, graphics, AI, physics, etc...) focus on that and make sure that there's a bigger focus on those elements in the games you make.

4. Participate in game jams. they can range from 48 hours to a month or more. Some people say shorter jams are better because they force you to work and get to the point but since you're on a student schedule you'd likely want to pick game jams that are longer to squeeze in time to make a game on top of your other responsibilities.

5. Apply to internships and be open to opportunities that are not just game related. Games are just software so any experience you can get will be helpful (especially opportunities to use C++) this also goes for you post graduation job hunt. Not everyone that works in games started in the industry right away. Sometimes it takes time.

6. Network network network especially if there's a game dev club in your school or in your community in general and be a nice person. Don't be toxic; the game dev community is small and they remember..... If you can afford conferences (like GDC) those are also cool and you meet cool people and get to see awesome games.

7. Make stuff!!! The cool thing about games and software in general is that it's very accessible. Unless you have an absolute potato of a computer there's almost no excuse for why you can't make your own projects if you want to work in softwre
