When to use it?

1. If the platform you are using requires high number of downloads for easy discovery, like Android/iOS app-stores , chrome-store , browser plugins/extensions.
2. If your audience is a "first-time" gamer, which never payed for a game - as this is a great barrier for download.
3.

1. [strong]  some levels are free. You need to buy the game to unlock a bulk of additional levels.
2. [medium] some levels are free. You need to buy levels , one by one. It`s a bit weak as if the user need to buy 0.5$ level two times in an hour, s/he will think again whether to buy the next one.

Unity Networking is easy? part -2-

For a FPS-like game, a good networking implementation need to have few points:
[It`s a summary of  a article on HalfLife networking]

Client-side

• Client-predication - user input cause immediate change in the game , but can be fixed later in the server overrides it.
• Interpolation - always add a delay of ~100ms to all other-users. Even if their ping is really small. Thus when you draw their location you will interpolate real, past positions with the exact positions.
• Extrapolation - on in the case of severe latency problems, the interpolation delay may not be enough and you simply don`t know where the user is right now.  Here you extrapolate future location from the last known ones, but as with any extrapolation, it`s not accurate.

 Server-side:

• State calculations and communications.

• lag compensation - if you trust client shooting-report, no need for this.
  If you don`t and you want to prevent this type of cheating, you will need to get the shooting direction and calculate hits yourself.  As the client is running in old-time, you will need to "re-wind" the players positions and calculate the hit in the old times.
