10-40% of expected show up at best. Whats your experience?

Expected number is kinda hopeful number. For more popular games with more people joining, sure, expected number could be fulfilled, but in most cases when: - game is not free - game has DRM - hard to be configured - requires extra effort to set up - crashes, has compatibility issues etc. - has discord community for extra communication - session has no server IP address, name, instruction how to join - lacks newbie description or attached guide - session is running when most people are at work It's hard to expect those who might be expected to join
