You've started down the road you'll never forget. We want to welcome you to the game programming world.
There are several keys to making a successful game. The first is the fun factor. Consider Command & Conquer Generals.
The fun factor in that game is huge. The second is ease of play. Consider Tetris.
Regarded by many as the greatest game of all time, it is incredibly easy to play.
Third is a good name. A name must be earned. Consider Westwood. Until Command & Conquer came out, they were ignored.
From the release of C&C to the time they sold to Electronic Arts, they were immensely popular.
Above all, make sure your games are interesting and engaging.
Take all things into mind when designing and building a game.
Anyway, I hope you do well. Good luck!
