Quick answer: Offer both: quick match for instant games via matchmaking, and lobbies for custom games and groups, sharing the underlying server allocation.
Some players want instant games; others want to set up a lobby. Offering both serves both. Here is how to structure it.
How to fix it
1. Quick match for speed
Provide a one-button matchmaking path for players who just want to play now.
2. Lobbies for control
Offer lobbies for custom rules, team selection, and playing with a chosen group.
3. Share the backend
Back both with the same server allocation and identity so you maintain one system, not two.
Catching the ones you can't reproduce
The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.
Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.
This is where a tool like Bugnet earns its place. Its SDK captures every backend error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.
Most of the time the fix is small. Seeing the failure clearly is the part that actually costs you.
