This is for a conceptual class project. Suppose we created a non-mobile game and also needed a separate app or client that connects players so they can play together. Is there a reasonable way to estimate the development and hosting costs? The idea is still early, so I'm mainly looking for the factors that would affect the price and a rough range for a simple prototype versus a production-ready system.

There isn’t enough information for a meaningful estimate yet. The cost depends on whether the app is the actual game client, a lobby that connects players, or a companion app communicating with a game server. Player count, matchmaking, synchronization, platforms, security, and whether you need persistent accounts or databases can all change the scope dramatically.
For a class prototype, you could potentially build a basic version using free development tools and free service tiers. A small lobby, a simple server, and a limited number of test players might cost little or nothing besides your time. You’d still need to account for debugging, hosting limits, and any networking or backend services you choose.
That estimate only applies to a demonstration. If the project needs to support real users reliably, you’ll likely need paid hosting, monitoring, authentication, testing, and ongoing maintenance.
A useful way to estimate it is to split the project into parts: game development, the player-facing app or client, the multiplayer server, matchmaking and accounts, databases, and hosting. A small student prototype might be built over a weekend or a few weeks with existing frameworks, while a polished commercial version could require several developers and ongoing infrastructure costs. Before estimating, define how players connect, how many players a session supports, and whether the app is replacing the game client or simply helping players find and join games.

Exactly—the connection itself may be simple, but keeping multiple players synchronized is where the complexity usually appears. You’d need to describe what the game server does and what role the separate app is supposed to play before pricing it.
