Prospect theory[Finance]
|
Having been a huge fan of the first Splinter Cell, and an even bigger fan of the Splinter Cell: Pandora Tomorrow, I couldn't wait to get my hands on this game.
I am already very familiar with the game play, but for some reason, Ubisoft decided to change the behaviours of the buttons. Many standard Xbox controls don't work as expected, and some of the changes are a bit awkward.
But one of the biggest gripes is about the loading time. Understandably, Chaos Theory is stretchign the limit of the Xbox. Still, the loading time is unacceptable. Resuming a progress save for the first time after coming into the game has two consecutive loading screens. It just shouldn't happen.
Also, the biggest change is that there are no longer any checkpoints. I think the genius of the first two games was that the game designers designated very well the part where you can save, which makes every move close to the next checkpoint all the more important. But now Chaos Theory allows save at any ti!
me, and for a stealth game that can blow any minute, it creates a temptation to save after every little conquest. But the saving time and restart are time consuming. So the game no longer feels coherent. It's partly my fault, admittedly, but that's because the game was designed to allow this kind of game play.
Also, the dialogues try too hard to be funny. CustomerReview by amazon

Prospect_theory
The prospect theory was developed by Daniel Kahneman and Amos Tversky in 1979. Starting from empirical evidence, it describes how individuals evaluate loss|losses and gains. In the original formulation the term prospect referred to a lottery.
The theory is basically divided into two stages, editing and evaluation. In the first, the different choices are ordered following some heuristic so as to let the evaluation phase be more simple. The evaluations around losses and gains are developed starting from a reference point. The value function which passes through this point is s-shaped and as its asymmetric implies, given the same variation in absolute value, a bigger impact of losses than of gains (loss aversion). Some behaviors observed in economics, like the disposition effect or the reversing of risk aversion/risk seeking in case of gains or losses (termed the ''reflection effect''), can be explained referring to the prospect theory.An important implication of prospect theory is that the way economic agents subjectively framing (economics)|frame an outcome or transaction in their mind affects the utility they expect or receive. This aspect of prospect theory, in particular, has been widely used in behavioural eco!
nomics and mental accounting. Framing and prospect theory has been applied to a diverse range of situations which appear inconsistent with standard economic rationality; the equity premium puzzle, the status quo bias, various gambling and betting puzzles, intertemporal consumption and the endowment effect. Another possible implication of prospect theory for economics is that utility might be reference based, in contrast with additive utility functions underlying much of neo-classical economics. This hypothesis is consistent with psychological research into happiness which finds subjective measures of wellbeing are relatively stable over time, even in the face of large increases in wellbeing (Easterlin, 1974; Frank, 1997)
