If you head over to the Programming Help section, you will see threads on how to make games.
Unfortunately it isn't as easy as it sounds, and you will require a program (possibly costing lots of money) to do so.
However, you can always try a program like Game Maker, which will allow you to create games (it can get tricky though). Games made in this program cannot be submitted to Armorgames though.
if you want to make games, you are going to have to have a program and like kingryan said:
(possibly costing lots of money)
you might have to buy sofware. I wish that making games was easier.But for a good game there is going to be alot of effort put into it.Possilbly too much effort for people like me, you, and probably many others to cope with (I dont know about you but i dont have a very Short attention span) Therefore, i dont have the patience to make a game i just play them.
