Guilds

[Obsyd]

So we decided that we will have three main guilds in the game that the player can join. When the player joins a guild he/she cannot join the other two guilds. Each guild will send the player on different paths, but eventually will lead the player to a similar ending. There will be quite a lot of things that are exclusive to each of the guilds.
For example:
-crafting recipes
-lore (example: if you find an ancient staff, only the mages guild will be able to help you learn about it)
-weapons
-armor
-teachers (and with teachers, skills/spells)
-quests (obviously..)
-seeds (for your farm)
Joining a guild will not be so easy. You have to prove yourself before a guild accept you. When you get accepted you will be an initiate and if you help your guild you will receive a higher rank.

What do you guys think about guilds? Any ideas or suggestions?
