I have a few suggestions/comments that I would like to share.
First and foremost, I think the main thing HeroCraft needs, is it's own client. I know this has already been promised for Minecraft's official release, but It, in my opinion, will be one of the majour drawing factors into the server. Now, Herocraft is unique, yes, but it's not hard to be unique. Being the "Best" Rpg plugin is merely a matter of opinion. There are other rpg plugins, that are just different, and some people prefer those over Herocraft. I, myself, DO think Herocraft is the best, just sayin'. Anywho, Dealing with normal plugins in Bukkit can only go so far really, because at the end of the day, you are just changing minecraft, never really adding. To have your own client just opens the floodgates for new oppurtunities, and quite simply, the possibilities are endless with a client. Now, I know you know all this, and again it has already been promised for release. I just felt I would state my opinion on the matter.
Second, I would like to see a total revamp of the town system, as was mentioned in the meeting. I think abolishing townships as they are now, and going with the 4 kingdom style, will increase A) Guild importance, B) Teamwork and C) Rpg feel. Right now towns are great, but they are just... small and powerless, to be honest. You can argue all day long that they are powerful and huge, but if you compare the scale of Minecraft to the scale of the townships at the moment, you will see my point. There is too much strife and too much competition. Too many lies and spies and thieves and glitchers. Most towns only have about 10-15 active members. Now, take all the active players on herocraft, and divide that by four. You start to get large communities that would be (forced) to work together. Not forced per se, but not allowed to feud within each other. Also, you could have a hierarchy system in the 4 kingdoms, with the abolishment of towns, a tax could be put on chest shops. Less tax for players in your own Kingdom, of course. Guilds would essentially take on what the abolishment of towns would set free. A) Smaller sub communities, but still subservient to the Kingdom (I.E. 2 North Guilds can not be enemies of each other, else it would lead to the disbandment of the guilds and/or exile of guildmembers) B) Guilds would be the victim of your raids C) Guilds help establish order. And with the larger player counts in the four kingdoms, the thing we call "Wars" currently in herocraft, which is basically raiding a town for a few days, would actually be real war. North Kingdomers would kill Southrons on sight, all while the western Kingdom is hiring out mercenaries to both sides. The RPG feel would be enhanced by this as well, because again it would have larger amounts of players on one side, enabling player-made quests (Or Servermade) to be made. (I.E. If East Kingdom is making a huge forest, they could start a "Quest" for players to bring in 4 stacks of dirt, for a 10c reward.)
Third, is having another vanilla server. I know this also has been brought up, and Kainzo has displayed support for this. The only problem, however, is how to deal with it. If you want a true vanilla server, then you can't have plugins. You can't say it's vanilla "But it just has permissions and logblock and NoCheat... but other than that it's vanilla!" That's just not right. Now obviously, you can't just say, "Don't hack Kiddies! Don't grief! Have fun!" because that would only breed chaos. And Chaos does not equate to Hardcore. You would have to find some way to limit the server, like making it invite only or such. And the server, in my opinion should NOT be like herocraft. Minecraft vanilla, how it is designed, is not meant for raiding each other or otherwise being complete dicks to your neighbors. It's called "Survival Multiplayer" for a reason, not just "Multiplayer". You survive the overpowered skeletons and reach haxing zombies together. Not constantly living in fear that your house will be burned down, your enchanting table destroyed with one punch from an enemy, and your house being forced to be made in the side of a mountain with a secret entrance. Now people, especially those who are used to herocraft, will want to do this. And since vanilla is infinitely harder to regulate than a plugin-filled server, it would also have to be invite only, or some other solution. Is it so hard for enemy towns to live next to each other in peace, fighting off those horrid creepers that 1 hit you from 4 blocks away?
My fourth and final topic is the maturity of people on this server. Now, recently I have been slowly sliding into some sort of drowse, taking it as fact that this server is full of mature people, who are not just complete douche bags. Last night I had a rude awakening. Dazureus, Whitemagehealu, and I all had a nice house on the Pre-Release 4 server, on the mountain next to Apherdite's and Shadowall's house. We all were hanging out, and shadow, who is (I think) in an enemy town in HC, was a friendly guy. We helped each other out, and it's was overall a fun experience. It didn't matter what happens in HC, we just wanted to enjoy the game. Now, after we had been playing for a while, and gained a good amount of stuff, a player, logs in for the first time, and for no reason at all, decides to wipe us dry from everything we have done. There was absolutely no point in this except to be a complete jerk. The Pre-Release servers only stay up for what? A week? It's made for testing and just having fun. Not being assholes to each other and overall not getting anything done. I was just so shocked that someone, from this server I was assured was full of mature people, would go on ANOTHER server, with no connection to the main HC, and merely be an immature child and destroy what I and the guys had spent 8 hours working on. I had been sick for 2 days, Sunday and Monday, as a few of you IRC guys know, and I was bedridden. The only thing I had was my trusty laptop. On sunday, I made a few vids on me playing legit, and on Monday I spent the whole day having fun on the Pre-Release 4 server. I just find it appalling how immature this act was. Now, this is partly a rant, but I am also trying to get across a message. Why do I, and most everyone here, play this game/server? To have fun. Believe it or not, it is possible to have fun without ruining someone else's fun as well. I hope you, the reader, understands that we are all just people having fun. None of us really hate each other, we just get frustrated in game. At the end of the day, we all have had a good time, hopefully.
Thank you for reading.
