thread_title: Merge with payoff matrix

message: The Example states: "...if player 1 plays top and player 2 plays left...". I'm new to game theory and this is the first time I've read this page.
What is "top"? Are these the bottom, right, top and left of a rectangle? What value does top have? --> 4? What values do the other side have, if they are sides? etc, etc.
After reading this page I'm worse off than before I read it. Like many wiki technical articles, it's been written by someone with an in depth knowledge but lack of ability in passing this knowledge on.  —Preceding unsigned comment added by 82.41.42.125 (talk) 14:58, 6 May 2011 (UTC)
thread_title:  Comprehensive Example? 

message: I think there should be a page "strategic-form game" that links to this page. Many authors use the term strategic form instead of normal form.  — Preceding unsigned comment added by 140.112.177.67 (talk) 07:02, 6 November 2018 (UTC)

message: The term is used first in « The topological space of games with related payoff matrices can also be mapped, with adjacent games having the most similar matrices. » and then in « The payoff matrix facilitates elimination of dominated strategies, and it is usually used to illustrate this concept. » And those sentences are not accompanied by any definition. One may think that the definition is trivial but it is not: for a two-player zero-sum game specifying only one real number for each pair of moves of the 2 players is enough thus the payoff matrix can be real-valued, but when the sum is not 0 (or fixed) one must give 2 values for each entry of the matrix, which is thus not a real-valued matrix -unless one introduces a coding of pairs of real numbers but that is not standard practice.
In the first sentence quoted the expression « the most similar matrices » is similarly undefined. And more generally i find the presentation of this page rather imprecise and in some places wordy. For instance « graphical » in the first sentence of this page links to the "Graph" wiki page, thus "graphical" is implicitly defined as "relating to or in terms of graphs". But "graphical" could well be interpreted in the more habitual sense of "relating to or in the form of a diagram or an image"; and an extensive form of a game is not just a graph so if it is "graphical" then this term rather means "in the form of a diagram".
