I want to have massive map sizes, placeable weapons, thicker jungles, more realistic lighting, helicopters, pitch black night time, object physics, customizable game modes, better ladders, water physics, prone, lots of object to chose from, lots of textures, and grass that doest rotate while you turn. The single most greatest thing they could include would be AI!!! They could either defend, patrol, attack, or whatever!! That'll add a whole new awesome dynamic to the game. Make your own single player or coop missions, or just have tdm with AI tryin to kill you too.
That would be good and if you could customize the bots, like choosing load outs and appearance and skill level, and choosing if they are aggresive or cowardly. You should also be able to place different types like zombies, you could have zombies attacking your team(map editor to make co-op modes would be good) having animals would be good to like having crocadiles or sharks in the water that attack you when you fall in the water, or tigers in the jungle that jump out and attack you.
a building maker kind of like the sims would be good. Split screen editing and being able to play on the map in split screen, split screen is always one of the things a look for when buying a game. Bot placement, weapon placement and game mode customization being able to customize loadouts specifically for the map. not necissarily vehicles that can't break or blow up but it doesn't happen so fast. tunnels. different scenery objects. small air vehicles. tools to help make realistic landscapes specifacally mountains. being able to customize the hight of ladders. more vehicles, more weapons.
1. Make bigger maps. Map editor maps are 10x smaller than SP map.
2. Pick a background environment. I would like to see an extra environments that you can add around the your map. You have just one square where you can build stuff and around that, you just have an empty place. For example you pick up mountains (woodland, jungle...), forest or a city.
I have to EXTREMELY disagree with this one. It cramped up the Mutilplayer for FC2 because mappers had to gimp their maps due to over abundance of snipers. I say that weapon placement is a better idea because it helps the author of the map control the flow of battle better.
