A problem I face however is that I should not buy a game of high quality for low price and then play it for longer due to the fact that it is so completely amazing. I'm slowly making myself through Half-Life 1 because if I play for long periods of time my time/cost/quality balance falls out of place. In fact if you look at my steam stats I have played Half-Life for 1.2 hours in the past 2 weeks. And that's been the average for the last 2 weeks as well. Which makes about 2.4 hours of high-quality playing time for 79p. That works out at 8p every fifteen minutes. This would be almost insignificant if not for the fact that Half-Life is one of the most entertaining games I have ever played.
Some people spend spend a long time on big expensive games which are of mediocre quality. This is wrong because they try to get more entertainment out of their game by playing it for longer while they save up for the next hugely popular game. But you can't get more entertainment out of a bad game by playing it for longer.
And that is why when my laptop arrives I will set up a new Steam account and buy many independent games at low prices, but not necessaruily play them for long.
You can also relate this to the completion of mock test papers to be completed dutring the holidays by replacing cost with oportunity cost. I should really draw a graph later on to represent this.
