I honestly don't know (and I challenge anyone who claims they do). When somebody quits a game it is never usually for just one reason. Is someone who *loves* the game suddenly going to quit because the injury level is changed? Very unlikely. Could someone who already has a list of things they are not that plussed about quit because injuries are changed? Maybe. The issue is further complicated with something like injuries because people that hate them do so for straightforward, tangible reasons (OMG my star striker got injured so I lost the cup final!!!one!!!), whereas those that like them probably do so subconsciously, knowing that they add to the game somehow but not really being able to quantify how/why very well. If it were just a case of "less injuries = better game" why does every single (decent) football sim, including those that don't have 'red packs for you to buy', choose to simulate them?
Anyway this is somewhat off-topic for the thread. If you think there should be less injuries then fine, you're entitled to that opinion, there's no right or wrong as it's just a value judgement. The thread is supposed to primarily be about whether the injury rate is *realistic*.
