you basically, select the type of game, eg racing fps, and then select the player the bullets you shoot enemy bosses levels object, theres a level editor that allows you to place objects,and enemys, ou can resize enemys and change the texyures around, but thats just about all you can do
if you make on game, the next game will look very similar to the 1st one,
if you are short on money i strongley suggest you get, dark basic, or if youve saved up enough then get darkbasic pro,
however coding, when you start off is pretty hard, but once you learn some basic commands and make a text adventure game, then youll carry on from there and make bigger and better games, the main difference from t3dgm and db/p is that when you code, your not limited by, amount of enemys ammount of levels, if you code you can make whatever you want, if you look on the showcase located on the game makers, main page you can see all the games made in bark basic/pro.
