I've been playing this game a LOT recently, and talking about it on Shoutbox, where it became a meme for a while, as we all bugged Crispy to set up a server.
Jokes aside though, this game is absolutely awesome, still in Early Access and under development, but for my money, the culmination of all the survival-type games that we've been inundated with lately. Ever since Minecraft, everyone has been trying to hit that sweet spot of survival gameplay. Games like Terraria, Starbound, DayZ, Rust, etc. But 7 Days has the most fleshed out and enjoyable gameplay of all of them, at least in my opinion.
It's not perfect, the end game could use more stuff, but still being in development, the devs will get a chance to add it. Still, it has a ton of content, and nails all the things other games fail at. You can build and craft whatever you want, like in Minecraft, but the building and crafting trees are way more complex, and the challenge is fine-tuned so much better. In Minecraft, you can build almost everyting within the first hour or two of gameplay, once you know what you are doing, whereas in 7 days, it will take you a long time, and you have to partake in things like exploration, scavenging, travel, trading, and combat in order to get it done.
The way scavenging is worked into the game is also brilliant and contributes a lot to the game. You get to explore many abandoned cities per every random map, and each one contains all these different buildings and points of interests. Breaking open safes or sneaking into a dangerous area or hitting up the trader gives a casino-like thrill, as you anticipate what you might obtain.
The combat is not perfect, there are some hitbox issues, but all-in-all, its fairly enjoyable. You get a lot of weapons to play with, lots of different types of zombies, some of them truly scary as you ramp up in level.
If you enjoy survival-type games at all, a very STRONG recommendation.
Oh, and
Crispy, where's the damn server?
