So the setting is Mars. But not in the current time period we all know of. We are on Mars during all but forgotten time period where there are feudal lords; great warlords with mystical powers beyond those any earthling would have but Earth is still in the Crustaceous period or something.
It has been suggested my concept was an Action RTS or a Multiplayer Online Battle Arena. Mostly I am considering using Hero Engine free license because that's where my budget lies. If its good enough for an MMO development it should be for a lesser networkable game.
Anyhow, there's no capture the flag. Instead you lay claims on resources such as wood and ore then you build from there to create your own weapons and armor. No alts in this game, every character is expected to craft as well as defend itself. There is going to be a magic system. But I'm heavily skewing towards a sandbox skill system rather than a set class/ leveling system.
Going to be as close to instant gratification in this game as can be realistically provided. It might be free to play but not with bloated content expecting people to spend months on end or years leveling before they unlock the fun stuff.
Some concepts I'll leave out of this original post.
I think 3D person shooter is good style , since you don't need buildings so it is not really RTS .. more like LoL I suppose , and 3D view will be better in my opinion and because most MMO's use it .
I think 3D shooter would work, possibly with an option to view from top-down when building?
