Why you should play old games

There are basically 2 main reasons:
1) You don't need the last hardware technology to play them.
2) You can buy them in platinum edition or even better prices (by Steam, for example).

So, you can play great games in you a bit old computer just spending a not so much money. And some old games really deserve to be played.
Some time ago I found Clive Barker's Jericho for a really good price (4€). Some time ago I played Undying (also based in Barker's stories) and I really loved this game, so I thought that for only 4€ I could take the risk. But I found a game better than I expected. The story is not as awesome as Undying's one, but it's also really interesting. I like its gameplay (team shooter) and graphics, and the characters.
Anyway, it's not a 8/10 game, but it's much more game than what it costs. So, it totally recommend this game.

Heisenberg Uncertainty Principle

You can't get the position and speed of an electron without altering the stats (http://en.wikipedia.org/wiki/Uncertainty_principle)

That sometimes happens in human relationships. You can't always ask to somebody or speak about a problem with that person, and don't expect to change his behaviour.

For instance: imagine that your mate has a behavior you don't like. Maybe the way he/she laughs. If you talk to him/her, he/she could try to stop laughing in that way to please you. But that could make your mate unhappy, because had to change the way he/she it for you.

Does our happiness deserve to change other people?
Does a relationship deserve to be broken when you feel you need to change your mate's personality?

As usually in life, you can't answer yes or no. It depends of the circumstances.
