So I have multiple ideas, some are already mentioned, and some may have been mentioned by others, I am just bringing up MY ideas about them... kinda.
1) Guild lots. I was thinking each guild could have their own lot, or village to be exact. Each village comes with like... 100 (If that's the guild max) houses. Each guild member can claim a house in the guild village. The houses are fairly small, because well, the members have their own lots.
a)(another idea under guild lots) And I was also thinking if there could be teleports within the houses. Like say... You have a lot yourself and own a guild house, you can purchase a house teleport and link them then. The teleports would only work where you can place them, so you can't link your friends and yours, because you don't have building perms!
b) I was also thinking maybe in each guild lot was a main fort type thing. The guild could have a level, and as it levels the main building upgrades! The guild could level up by fighting/crafting stuff like that, or it could level up with money and players... Meaning. The guild must have (x) so many members and you must have (x) amount of coins (whatever we are calling them) to buy an upgrade.
2) Guild symbols. Well you know how each guild has its own symbol and all. Why not show it off? Maybe each guild could have a cape/shield/shirt thing with their emblem? At the beginning of creating the guild they would choose which one to have. Then it would be given to any guild member, and of course, taken away if that guild member left.
3) Guild trading. Maybe in each guild (What I am gonna talk about is fitting for a guild lot, but it can be just in general if there wasn't a guild lot) there could be a vendor/booth, where the guild can trade amongst its members. All the members have to do is stop by, list/sell an item, and it would appear for others to buy/trade for it! It would be easy enough amongst guilds, and that way the people could help others out by giving them gear. Yes yes, they could always trade, but this would make it so one person could see MULTIPLE peoples trades, not just one, and they could see which is the best deal as well.
4) Guild boards. There could be in a guild lot, a guild board. Also known as a notification/updates board. The leader, or higher ranking members with the privilege, could post updates on this board about raids/events/battles/info. One flaw to this is some people may take advantage of this and use it poorly. Well the board COULD have a censor, just like the chat, in fact maybe the same censor! That way it would be like, don't write it unless you can say it. Anyways I think this would help the guild members remember important stuff easier. You could always say it to them, or send a mail. But what if you have a lot of members, do you really want to do that however many times? And what if they forget! Well whatever is on the board would stay there until its erased, and so people could check it.
---Now this is just not related to guild's mainly---
5) Open world dueling. I don't know how to say it any better. Open world dueling would be like... If someone asks you to duel you would duel right then and there for all to see you fail... Or win... I think this was mentioned before by someone else... Before the whole forum was deleted... Anyways it would be kinda fun, and good for filming purposes... Yup that's all I think about... It could be laggy though as well, but if the game could support a lot of people together than it shouldn't be.
6) Mail! One thing I hated about FreeRealms (shoot me now I said hate) is that there was no mail, or option of leaving a message to an offline friend. I think this would be a GREAT idea. Whenever I wanted to talk to a friend I would have to wait, and you know what, some of those friends never came on when I did! Mail would be amazing to have so that you can pester that friend who is never on, or spam that mean jerky ex lol...
7) Gifting. This somewhat goes along with mailing. You could mail a gift to a friend offline, or online. I guess you could always trade... But still, what if they weren't on, no one likes to wait to give a surprise gift!
OKAY I think I am done, and as Star commented, I write long threads, her quote "really long threads". CYA PEOPLE!
