Would it be correct to say videogames from the last 10+ years are generally targeted at an r-selected audience?Yes, this is almost certainly true in the broader sense. It is probably not a conscious design decision made by someone conversant with selection theory, it's probably just an attempt to make things more "accessible" and "appealing to the casual player" that reflects the larger cultural shift towards the r/selected population. But the essential effect is the same; one could even build a mathematical model demonstrating this by comparing the average number of player-lives lost in a similar time period in one game versus the other.
The first time I noticed a change in videogame mechanic and map design was when I went from playing the multiplayer mode for Modern Warfare 1 (released in 2007) to playing the multiplayer mode for Modern Warfare 2 (released in 2009).
In Modern Warfare 1, the generally larger maps meant more open spaces and sections of the map off the beaten path. The maps were large enough to sneak past the enemy team or attempt flanking maneuvers, even with two teams of 24 players. This map design discouraged running around like a headless chicken, because the snipers on the other team would take you out in seconds if you played that way, and it wasn't fun to spend all your game time doing the same 30 second run from your team's spawn. The game encouraged more investment in each life and a longer time preference. The maps in Modern Warfare 1 encouraged cooperation and thoughtfulness.
In Modern Warfare 2, the generally smaller maps had fewer open spaces and sections of the map off the beaten path. Most maps were crowded with two teams of 9 players, and the maps had pretty direct routes that funneled the teams toward each other. This map design encouraged running around like a headless chicken, because most of the battles were fought inside the 10-yard range. If you used your explosives and took a spray-and-pray approach, you'd probably take somebody out before you died yourself. When you did die, you'd respawn with a full loadout, usually close to the action. Modern Warfare 2's maps discouraged cooperation and thoughtfulness.
I'm interested to know if you think r/K selection applies to videogame design and the games' intended players.
In the game that appeals to the r/selected, the number of lives would be higher, the average in-game lifespan would be shorter, and there would be less benefit to being patient and exhibiting longer time preferences.
