Quick answer: Yes, you need playtesting, it reveals how real players experience your game, where they struggle, crash, or quit, which you can't see from your own expert play.
Playtesting shows you your game through fresh eyes. Here is whether you need playtesting.
Why You Need It: You Can't See Your Own Game Clearly
You need playtesting because you cannot see your own game clearly, you are an expert player who knows everything and does not struggle where new players do, so you cannot judge difficulty, clarity, or where players get stuck. Playtesting reveals the real player experience you are blind to.
Bugnet captures where players hit crashes and friction (via breadcrumbs and drop-off), so playtesting surfaces the points where real players struggle, which your expert perspective hides.
The Catch: Capture What Testers Hit
Playtesting only delivers value if you capture what testers hit, since most testers (like all players) do not report the crashes and friction they encounter, they push through or quietly stop. Without automatic capture, you lose the hard behavioral data that is a playtest's most valuable output.
Bugnet captures crashes from playtesters automatically with full context and breadcrumbs, so you get the crashes and friction points they hit, the hard data that makes a playtest actionable, not just opinions.
When You Need It: Throughout Development
You need playtesting throughout development, especially before launch, to find the friction, confusion, and bugs that real players hit. The earlier and more often you playtest, the more issues you catch before they reach your launch players.
Bugnet captures crashes from your playtesters' devices, so each playtest surfaces the device-specific issues and friction points, getting more signal per test session than relying on tester reports.
Yes, you need playtesting, it reveals how real players experience your game, where they struggle, crash, or quit, which you can't see from your own expert play. Just capture what testers hit, since most won't report.
