Advices on creating a lobby system for my multiplayer game

[sterile spindle]

Hi everyone, I'm currently developing a small multiplayer game for a university project, and I'm trying to understand the best way to approach the lobby system.

Could you please give me some advice on the main steps to create a working lobby (player connection, room creation, matchmaking, etc.)?
Also, I’m not sure whether I should first build a proper GUI for the lobby or start by making everything work with a simple prototype interface, and then refine the visuals later.

Any guidance or resources would be greatly appreciated! Ty

Really depends on which backend solution you want to use. Unity, Steam, Epic, and Playfab all have different solutions for Lobby/Matchmaking. Reading through their docs will walk you through getting set up

i was thinking about steam

With Steam you can use Steamworks to manage lobbies and do matchmaking. Either Steamworks.Net or Facepunch work well with Unity
