With recent threads regarding TES: Online (and others) often becoming discussions about what MMOs should be like rather than about the game the thread was created for itself, I thought it might be a good idea to create another of these threads. Afterall, we're all here on this forum because we love, or at one point loved, MMOs and all of us probably want them improved upon or see different iterations of them.
I urge people to refrain from talking about "I want a MMO in the X universe" because the discussion I'm looking for here should be about mechanics, basic setting, aesthetics etc: Everything that every MMO has in one shape or other but we don't have to be so specific as to talk about a already known IP.
Personally I have grown tired of the "Themepark" MMOs. Reason? I see them as inferior games that have to put a carrot on a stick in front of you to keep you playing, most of the time I play these kinds of games, like WoW or SWTOR, games with gear grinds, without even being mildly interested as I know that I'm on a long hike towards the gear that will allow me to enjoy the PvP of the game. Due to time constraints I often never reach that goal and I'm stuck in a cycle where I'm aleays at least one step behind and never get on equal footing gear wise compared to the majority of the people who frequent PvP.
I'm looking for a sandbox game with a big open world where every player can be an asset or a danger. A game that doesn't have levels or gear in the traditional sense but rather has gear drops as solely cosmetic things and a combat system designed around skill, reactivity and adaptability. Think Dark Souls, where a fully armored knight will move slowly and hit slowly yet hard, and a rogue-type character will be nimble and quick but won't last long at all in combat and due to using lighter weaponry will deal less damage. Something like that, I really think it could be done with the technology of today if someone is willing to push some boundaries.
A game with a large open world with city and/or castle building by player guilds or equivalent, wars between said guilds over territory and strategic points, and so on. I am certain that there are games that have had some of these features, but not all of them.
