Achievements are only as good as the achievement is. Sometimes, they ate great for being really good or trying a challenging playstyle. Sometimes, you are rewarded for bad playthough or othertimes you are trying to get the achievements before your other friends get to complete them. Ever played an online match and someone dies 5 times in a row to get an "achievement"? It just enables bad play. I only do the ones that are interesting and ignore the rest. Depending on the games and sims that I do though.
I am aiming to get alll achievements in flight sim
