Software Engineer at Glance Networks
Game development teams typically have designers, programmers, and testers on staff. The elite programmers in most game teams typically have skills in computer graphics, high-performance software, and maybe artificial intelligence. So, you can get a computer science degree with a concentration on computer graphics to prepare for a game dev job.
Also in gaming these days you'll find people working on the business side. Handling such things as "in-app payments" is part of gaming. So is handling web sites supporting the game.
When you see a job opening, read the fine print. You can usually tell what sort of work they want you to do from the skills they ask for.
But, please, BEWARE! Many people hope to break into the game dev field. From the point of view of the executives of game studios, this means the talent pool is very broad. Therefore, the internships are longer, the wages are typically lower, and the job security is inferior to that in other parts of software development. Make sure you acquire skills that are also useful outside the gaming field.
