There's some very good suggestions
As someone who will never play these games ( not my thing), how is this implemented? I would assume that expecting users to rate other players would be burdensome and wouldn’t have the legs to work over a long period of time.
I truly like the idea, as the toxicity in online gaming is a primary reason I will never play these games, but I also wouldn’t want to personally rate the folks I play with every match either. Just lazy. But if it was easy and streamlined I wouldn’t mind it.
Just curious on how it all works I guess.
The commendation screen is shown for an unskippable amount of time (unless you quit the match) at the end of the match, before the post-match summary which is when you’d see the scoreboard, level progress, and battle pass progress. The commendation screen shows you the player cards of all 4 of your teammates, each with 3 buttons representing the different commendations you can give someone - one for being a good teammate, one for being a leader and helping coordinate your team’s actions, and one for dedication to the match. You can commend each player once per day, and for a given match you can give 2 commendations. Picture 4 columns with 3 rows. When you click a single row for a given column, that column is greyed out so you can’t commend that player again. When you click a second commendation, all of the buttons are greyed out. For the opposing team, you’re given a single button prompt: “was the opposing team fair/well-sporting? Press F5 for yes, F6 for no”
All in all, for commendations the game asks players to click 2 buttons and press 1 key. It’s extremely intuitive and if you’re stuck on the screen for 10 seconds, you might as well engage with it.
Anything that negatively affects a player’s reputation is done ad-hoc. If someone’s teamkilling or destroying their own team’s gadgets or intentionally making it difficult for their own team to win or using slurs or something, it’s up to individual players in the match to pull up the scoreboard at will, select their name and hit the report button. Otherwise, the game also automatically reduces a player’s reputation for actions the devs have deemed disreputable, like friendly fire, teamkilling and destroying team gadgets.
It’s an extremely easy system to engage with, and I’m really looking forward to when they start implementing more rewards for high-reputation players.
Dota 2 and overwatch does something similar, it's simply a quick click after the match above the players name.
Overwatch rewards you with battle pass exp and a symbol showing how many times you've been commended
Dota 2 simply shows you've had less then X amount reports and your behaviour score after X amount of matches
