Basic Trope: A game player only improves a few specific skills that s/he considers important for their character, and either ignores all other possible skills or takes penalties on them in exchange for even more bonuses.
Straight: Minnie puts a lot of skill points into her character Maxine's offensive capabilities, but not into skills that do not involve combat.
Exaggerated: Minnie sacrifices her legs and eyes for mastery of all magic. She never misses them.
Downplayed: Minnie gives Maxine one skill that's a little higher than most would expect.
There are things that the character really won't need to do. Nobody puts equal emphasis on everything that a character could do, rather they focus on what they are going to need more, and some people just go 1-2 steps further than everybody else.
Inverted: Minnie is an extreme Jack of All Stats whose "useless" non-combat skills save her life on numerous occasions.
Subverted: When Minnie tells her party about the stats/skills she ignored to focus on combat, she finishes by saying that she was only joking.
Double Subverted: ... because she could tell by the way they were looking at her funny that they thought she didn't know how to make a character effectively (and maybe she really didn't), and lied to hide her embarrassment.
Implied: During what is basically characters meeting with a Hero of Another Story and his group, Maxine seems socially awkward and a little dumb to the heroes, but while the characters are talking a loud crash is heard, and maxine has not only sliced open the large door blocking their way forward, which stopped both parties, but a high level enemy is seen slain in front of Maxine.
Deconstructed: The "worthless" skills come up in the campaign a lot more than Minnie thought that they would, and Maxine is incapable of doing the things that really matter.
Minnie doesn't complain to the DM because she knew what she was getting her character into, and actually rather enjoys role-playing Maxine as the arrogant Ax-Crazy that doesn't get the "real" world and needs to be taken down a peg every one in a while.
Plotted A Good Waste: Maxine was made to test the other players, and see how well they would take her into the story. When it's clear the other players are intent on screwing over Minnie rather than making a story around it. In the end the GM makes Maxine more unbeatable just to punish the players for being inflexible.
