Randomness isn’t the problem. Randomness—-used properly—-is an essential aspect of replayability for loot games like this. The problem is Bungie doesn’t obey the “rules” that other games of this type follow: [i]Progression and Accomplishments are based on player time investment and skill. Loot awards are random.[/i] But Bungie has resorted to distributing almost everything in this game according to randomness as a means of squeezing out every bit of replayability from what little content they create. As you’re finding out, being denied an achievement because of a loot drop that is [i]designed [/i] to drop at a super low rate, and may be time-gated, or locked behind a competitive wall (Gambit ship and sparrow) feels cheap and disrespectful to your time and efforts. Which is why more experienced developers don’t do such things. RNG isn’t a problem. HOW Bungie has opted to use it—-as a means of simply consuming playing time without reward or benefit to the player or play experience—-is the problem.
