Garry's Mod.
Now before you ask this is not a mod this is a game, and it is one of the best games of all time, as of yet I cannot find the words to pin point what genre this game is. Some people would jump to the word sandbox, i however dispute this idea as it is both American and far to broad to give any real meaning.
Ok, some basic gameplay points to help demonstrate what exactly this game is:
FPS Section:
If like many of the adrenalin fueled gamers you fall into the category of receiving a massive rush after having taking the scalp off of some poor, distracted by magical ponies, 4 year old American child then this game may be one for you. It accompanies a variety of gamemode which allow you to do just that and more, one such gamemode - deemed "Fort Wars" by its creator - involves teams building elaborate destructible bases using a sizable selection of props before the the killing begins, after which a montage of bullets and dislodge base fragments will be the only thing you can see.
RPG section:
Those noobs who see the pinnacle of RPG been elder scrolls have not met what it is to role play until they have experienced what Garry's Mod has to offer. 2 gamemode wage war within these borders, the first of which is "Serious RP" a gamemode that requires players to adopt a role in society and become both powerful and successful, however forget all that rubbish graphics & most of the work done for you, your simply given a well scripted gamemode and a tag with your job on it, true roleplay is a process of the mind fragmenting temporarily and allowing you to assume a new persona etc. The second contender of the RPG aspect of Garry's Mod is "Dark RP" a similar idea to the first with the bonus of it been slack, allowing you to build intricate contraptions to do the various jobs that are needed, these range from been a gun dealer to a drug dealer, a cop, the mayor, or in fact anything you can come up with.
'Sandbox' Section:
This is what I like about this game, it has a mode called "Sandbox", phun. This is all about gamers been dumped into a randomly large and beautiful map, and then well, erm ... yeah. What ever you want, design and build a car, using assembly write a CPU to produce complex holographic images, design a massive logic algorithm which enables the development of Space Invaders or a watered down version of WOW, all ingame.
To get the true scope of this section do your normal rounds on "Garry's Mod", if you don't know what I mean by this then your not a gamer, not are you even close to an internet user. Heres a hint: Youtube, Google, Wiki, etc.
Themed / Directional 'Sandbox' Section:
As many gamers who have ever been given freedom know some times ideas are more difficult that finding an online match on GOW2, so as a response to this many gamemodes have been constructed to allow you to build with a purpose, my favorite of which is "SpaceBuild" where gamers are dumped on a planet and told "Good Luck", of course you don't have to explore the many planets within the harshest of climates that is the vacuum of space, but what the hell. Constructing a spaceship is first required, after which the generation of resources such as Air, Energy and Coolant is required, then the life support must be rigged to your ship and its storage's filled. Finally freely explore massive maps, or mod your ship to change it from humble explorer to an American who is ever so slightly upset about the fact it is Monday.
Survival Section:
Many of us enjoy beginning with nothing and then becoming a dominant super power, as is the idea behind many RTS game and the American dream - which I might add is ultimately failure as with the impending climate change farming will become increasingly difficult. Anyway, the gamemodes here range from zombie survival, where gamers must attempt to subdue wave after wave of the undead, or an interesting gamemode know as "Stranded". This is a nice gamemode which mixed elements RPG skill training with FPS blood and gore and the American ideal that anyone weaker or less developed than you should be killed. Gamers are forced here to mind for various ores and chop wood, enabling the construction of workbenches and furnaces which enable better tools and more refined pure metals, eventually the production of guns and other tradables / killing implements become available and the gamers either band together in tribes or attempt to disembowel one another, some of which will be using spoons others 9mm's.
Ok, fingers tired need to get my tea.

This is not all the game has to offer, but im tired so you will have to see the rest for yourself, oh and by the way this is a multilayer game with single player capacity too.
**WARNING**
This game requires skill, and is not for mere players but is in fact for gamers, LUA programming and C++ are what you strive to achieve with this game, it introduces programing to you then allows you to develop and gradually improve your skills, it also offer the most dynamic gaming experience that is attainable at the moment. Another important note, those of you which admire graphics should know that the screen upon which you are now reading is flat as such ALL graphics are 2D!, anyone who so much as whispers the words "Graphical Improvement" will be shot on sight.
Remember Gaming, Touch, Sight, Smell, Vision etc etc, all take place in the mind. The mind is not part of the material world in which you may deem to live in, the mind generates and controls what you see, have it ignore graphics, despise them, and adore the gameplay instead.
