It probably wouldn't go over well with the community to all of a sudden start charging for a game that was once free. People would probably just continue to use the old version(s). Also, it would turn it into a real job instead of just a hobby, which might not be as enjoyable to me.
I did have an interesting idea, though. Instead of charging money for the game itself, I could have a fee for global login registration. Global logins wouldn't be required to play the game, but they protect your name and clan tag, and eventually will have statistics and maybe some awards/badges for various things.
Pros:
- The game as you know it now would still be free.
- Requiring payment would reduce potential abuse of the global login system.
- Server admins could require global login accounts to play on the server, thus filtering out most of the non-serious players. Naturally, admins could set up completely free servers that don't require registrations to play, too.
- Money earned could go toward advertising to help increase the game's popularity (as well as cover the costs of the login server).
Cons:
- As I've learned from the shirts I've sold, dealing with payments is a pain, especially from people in foreign countries or kids without credit cards (or worse, both).
- I'd have to take support a lot more seriously because people would be paying customers now.
- Lots of people may be turned off by having to pay for a login account, and thus there wouldn't be enough players on the (eventual) ranked servers.
It's just an idea. Thoughts?
