I think having zombies crocodiles and any other water enemies in the game would bring the water part to life as there are no water enemies in the game. Trees enemies would be great to because going near tree to chop them down would be more fun and keep you on your toes and alert. Because have some thing like monkeys or if not monkeys something else jumping out at you would be fun and also terrifying monkeys that can steal items and equipment to be fun and terrifying to if u are fighting horde of zombie monkeys or zombies all together off. We just need more fun and bring the game to life going around killing the same enemies every day will start to get boring for other players you want to keep players entertained to play the game not bored them. also have npcs that you can build a settlement with and be able to start a family with would be more fun and would give players something to play for in the game and not be bored just playing online or single player going around collecting supplies and building alone. Walking around the map alone killing the same zombies day and night in the game would get boring for some players. So having some hazards in the game in all areas would keep players alert like avalanche in snow that could damage your base in snow area would be fun and driving like mad in a snow or running for cover would keep player alert too by trying to get away from it would be fun. lightning that could strike u in a thunderstorm again would keep u alert and on your toes. Burning area fires as its the called burning biome for a reason desert wee sand tornado just like in the wasteland they had mines that kept you on your toes and the zombies dogs being their too. Again player want fun be entertained and stay alert with dangerous thing that can happen zombies that can jump out at u from water trees houses and so on not bored. Walking around alone killing the same thing can get boring for players building a settlement or a base alone can be the same for other players too. I get why that player is asking for all this but do you all.
I've responded to those ideas and repeating them doesn't change the response. Some things won't happen and some things might (see what I said above).
You seem to think that people will get bored of the game with how it is now, yet the game has consistently increased in the number of players and it has higher average gameplay time than just about any game other than service games like MMOs. Many players have over 1000 hours in this game. How many games can boast that if they aren't service games like MMOs? Even those who don't have over 1000 hours very often have a few hundred hours. And if you compared this game to others any one of those players has played, you'll still usually see this game having more hours than others they play.
That counters what you are suggesting because it's clear evidence that people DO enjoy the game without the things you are suggesting. I'm not saying new things will not make people like it more, but not having them isn't the cause of boredom. This game is going to be liked by some and disliked by others. If people get bored of it quickly, then it isn't going to be the game for them regardless of any additions to the game.
Btw, it is called the "burnt" biome, not the "burning" biome. The game is set a while AFTER the "apocalypse" and fires don't last forever. It was burned prior to the game, not during the game. Besides fire is a FPS killer, so they'll keep fire to a minimum as much as possible, especially if it's environmental fire rather than something like a weapon on fire or a trap that uses fire.
And if playing alone is too boring for you, play with someone. That will likely give you more enjoyment than playing alone. I usually play games alone, but this one I play with someone else all the time. If I only ever played it by myself, I would have a LOT fewer hours in the game.
