coding/game development is every nerd gamers dream.
it's nothing like you want it to be, and even if you begin to scratch the surface, it isn't until you actually have to code that it becomes horrible. absolutely, absolutely horrible.
id suggest, if your dream job is game development (primarily because you like games), to focus on something like storyline development. It's highly unlikely you'll get the job, but if you do, you won't hate it. coding sucks.
Other fields, such as modelling, database administrator, etc are also slightly better. At least you can get creative with modelling though.
Networking..oh god, take it from a network administrator for 3 years, it's a ton, ton worse than you hope it is. Maybe you like that stuff, I thought I did too. It doesn't get much funner than crawling under tables and stuff ziptying every wire together, or programming the router/switches. It pays high for a reason, its..its horrible man.
but hey, do what you want. if you dont like it, move on to something else. just keep your options open.
