I once made a shmup with a map editor and sprites and all that yadda yadda, but it died in a HDD crash so I can't even find an screenshot. I also made some silly opengl stuff for learning but I don't know if it'll become a game since I don't really know what kind of game to make.

I've been starting various game projects almost my whole life. Never finished one though, I always find some flaw in the concept that would prevent it from ever being a "perfect" game and then I get discouraged.
I may have autism.

I've been studying Video games design for a 5th year now and I'll be going onto my 6th soon.

It's easy but also hard, many game engines have alot of pre-built packages for you and with a new "Blue print" system sweeping alot of the software its getting easier (Blue prints are pre-built snippets of codes you can drag and drop together in a nice simple way)

You just have to come up with a good idea, fucking you can come up with a good selling app in a 2d game engine if it has a good design to it

I made a really bad zork/adventure style game once, in some Java class.

I made some games but they were all bad. I've started learning Android development, maybe I can make some games for that and make some money.
