What defines skill in video games to you?

To me, skill is defined by the players individual skill to pull their own weight and push through situations that would even normally would be impractical.

In single-player games, there's difficulty settings of course, the higher the difficulty, the more demanding the game becomes in that you might as well change how you play altogether. Granted, some games end up being more luck-based when the difficulty is at its highest (CoD4 and WaW Veteran), but still, the player's persistence applies.

Of course, enemy placement, the variety of enemies, and what the game offers in your aid is applied too, so in games like Quake, the game can give you a good beating, but it doesn't go to the point that the game is unfair since there's enough weapons and health to aid you, to which it promotes being cautious and aggressive at the same time.

In multiplayer, this is another breed, some guys have individual skill, some games are team-heavy, and some mix it both. Games like Quake accounts communication and individual skill heavily that basically the people who pretty much play this game religiously can see you from 10 miles away. Skill caps can keep games interesting in how much impact one player can do, which has been shown by better Counter-Strike players on games with everyone having the same ranks.

With this in mind, though it's probably a personal thing, games like Overwatch pretty much askes players to stick like glue at all times, but individual skill is pretty limited, causing games to feel mundane as players would feel like nothing is being accomplished, thus feels unrewarding. Not to say team-based games are limited in skill, but compared to TF2 where individual skill is still present enough that one player can change the tide of a game (Depends on situation) without the need to change classes constantly, well, I'm just confused.

Then you have like Call of Duty (Newer ones more specifically) where the skill is nonexistent since any player can do well, but only if they're lucky, compared to CoD 4 where anyone can have a chance, which means while new players can do well if they play right but someone better of course, well, would do better.

Anyways, enough of my blabbing, say what you think.
