Competition can often breed toxicity. I've actually found Starcraft to be less toxic simply because in the most competitive game mode ( 1 versus 1), there's nobody to blame but yourself if you lose. People tend to get toxic about using "cheesy" strategies or playing the "overpowered" race, but overall, the most toxic communities I've been apart of tend to be highly competitive games where team play is a key component. Some examples in my experience are games like Counter-Strike, Dota 2, LoL, etc. A couple common features of these games are: 1. Matches tend to be drawn out over at least 30 minutes, if not longer, forcing you to be teamed with people you may not get along with for a longer period. (Overwatch comes close to having this issue, but I still feel the shorter match times tend to limit extreme toxicity you can find in other games) 2. A single player actively working to harm the team, or simply not at the same skill level as the rest of the players, can easily sink the team's chances of success. 3. An individual matchmaking / visible ranking system which fosters toxic attitudes like "well, I'll sink your rating if I don't like you", since every member of the team is ostensibly trying to raise their rank. #3 when combined with #1 and #2 can create situations where "trolls" can easily ruin a game that may take an hour to finish and may even prevent any chance of victory. These factors tend to be key to the most toxic game communities I've been involved in.
