We should have some type of login system either integrated into Blockland or integrated with RTB. With having a login system we can have double security, registering will be free but then you still need to go and enter your authentication key to unlock the full version. You will have to enter your login every time you open Blockland or you could set it to Remember Me, and add-ons like RTB will not activate until you are logged in.
-Some Value Points-
1. We can get more security, and a login system is just nice...every single game has one.
2. Protection in RTB/IRC, people will not be able to go and view our friends list.
3. Profiles can be made each time someone who has registered and has logged in, it will show a picture of their avatar and ask for a password when they click on their Profile.
1. The login system is already secure. This idea just adds another unnecessary barrier. Instead of only needing to know the key, you need to know the password too. It's not going to change anything, especially not "security".
2. You can already stop people from accessing your computer. If you have to share a computer, you should still be able to make user accounts regardless, and if your parents seclude you so much that they don't let you have your own user account then there's probably nothing you need to hide anyway. It comes with all operating systems. Install Blockland locally on your user. Regardless, I can't imagine why viewing your RTB friends would be a drama. Do you have friends who send you furry research or something?
3. Again, redundant. Maybe a picture of your avatar could be on the main menu. But the profile system is pointless. The only reason you could possibly want to have multiple profiles is to have siblings playing on the same key under different names which Badspot isn't going to allow.
