Einstein was wrong: the people living after World War 3 (which happened in 1998) aren't fighting with pointed sticks and stones. It's still guns. The whole world is in fact still very much the same as we know it. If it weren't for a few details: Half of the population has mutated because of the high radiation and people are using flying 'speeders' instead of cars.
Tex Murphy isn't a mutant, but he has such a speeder. That's the only 'modern' thing about him, though. His trenchcoat, his whole appearance would fit more into the 1930s than in the present of 2037. To complete the cliché, he's a private investigator living in San Francisco (Los Angeles would probably have been too obvious...). Who else but a good-looking, young woman could possibly walk into his office and provide him with an assignment?
In the old, golden days, video games where thematically almost exclusively catering for a single target audience: male adolescents. Logically, some fantasy themes were recurrent: saving the earth and all of humanity or even the whole universe. Those were the goals and challenges of tomorrow's family men. Gaming having grown up, yesterday's youths are now confronted with reality. Those old dreams have been tainted as childish and the games industry now also delivers realism into the formerly well kept play rooms of today. One way of doing this apparently involves simulating every single job, no matter how absurd, and also every single every day activity, no matter how trivial, in a game. Resulting in increasingly obscure products in which the original ideas can hardly be recognized anymomre. Though even in the good old days, us heroes had to take a couple of collateral damage hits and, for example, resign ourselves to the role of a simple taxi driver. The implication being boring drives from A to B, where the highlight of the day is exchanging some gossip with the passengers. Unless, of course, it was Space Taxi.
Imagine the beginning of a great adventure: You are standing in a forest. The sky is blue, the sun is shining and the wildlife is wandering about. There is a guy named Jack, Steve or Brat next to you, who will turn out to be an invaluable source of information, for he is The Guide. With great foresight you brought a set of tools along, so you can start right away. What will it be? Do you want to start digging, to search for valuable ores and treasure caves? Or do you want to attack that slime creature that is coming closer, in the hope that it will drop some valuables? Or how about building a base, maybe a log cabin, first? All of this is possible in Terraria, an open-world 2D platformer, that combines the fun of exploration, fighting and building in one game.
