All work and no play makes Jack a dull boy. I couldn't agree more with this wonderful proverb. The first game made on a computer, titled "Tennis for Two", was way back in 1947 and later, in 1962, came the first popular digital game named "Spacewar!". Thereafter, man has been trying to expand the capabilities of gaming on a personal computer. Computer games and gaming engines have come a long way since then.

Passion for developing games had reached another level, and developers started giving out their work for free to people.

I've been asked numerous times whether freeware games are worth it and whether they give the same amount of enjoyment as other big name commercial games. The answer I give them is yes. In fact, I've had the most fun playing freeware games in this list.

The next question, which pops up in the minds of people, is why do developers give away their hard work in creating these games for nothing. The first reason is that game development is their personal hobby or passion, just like each one of us has a hobby. Secondly, they create a name for themselves and get appreciated by people from all walks of life and subsequently have a fan following. Thirdly, they might also get donations from hammer legion gamers and hence, earn quite enough bucks. Fourthly, some of them create games for their project works and get recognized for their work by bigger gaming companies.
