I got the beta for Don't Starve Together last week and started playing it over the long weekend with some friends. For those unfamiliar, it's basically Don't Starve, which was a fun little indie game by the guys who made Mark of the Ninja (a great game that everyone should play, by the way), but with up to six players sharing a world together.
If you haven't played or heard much about Don't Starve, I recommend it. It's a rougelike with (mostly) permadeath and tasks you with staying alive in a sort of horrific version of our own wilderness, where venturing out in the dark at night is an instant invitation to death and almost all of the creatures are hostile at least some of the time. It's a challenging game that will really force you to manage your time appropriately and always be working toward better gear and equipment to keep you alive so that you can keep yourself alive another day.
Don't Starve Together is more of less the same game but with friends. I prefer it quite a bit to the original game. While it loses a lot of the horror and isolation that is inherent in a game where you're one person and the world hates you and everything seems to be more dangerous than you are, it makes up for it by just being more manageable and fun. A lot of the frustration of never having enough time to gather all the resources you need is nullified when you have several people who can all focus their time on different tasks, and that's without us really being all that organized since we're just getting started with the game.
The game is definitely still in beta, though. It lacks a lot of the features and additions that were made to the main game over time, and currently lacks all (I think) the content from the Reign of Giants expansion. I'm assuming most, if not all, of that stuff will be added over time, and right now the game runs pretty well. My friends and I only had one instance of lag forcing me to shut down the server I was hosting. I'm assuming this issue was on the game's end, as we moved to TF2 and my ping was normal. Regardless, bumps are to be expected when you play an unfinished game, and that's the only one we've run into so far. I have at least half a dozen mods running to augment the game and it has yet to crash on us.
And, oh yeah, mods. The game has Steam Workshop support, so all you need to do is subscribe to a mod in the Workshop and the game downloads it automatically. All you have to do is then enable the ones you want in the Mods tab when you load up the game. As far as we could tell, the mods worked for everyone in my server without requiring my friends to also subscribe to them, so that's points for ease of use.
The mods vary from adding new characters (DST only has a couple from the original game at present...one of the mods adds several more), adding functionality (one adds a minimap that you can toggle on and off while another adds icons for any players you've met in your world that shows the directions they are in at all times), and some just make the game a little easier (craftable gears, for example, which can be difficult to find and are very useful). Regardless, mods make the game more fun and customizable.
All in all, I'd recommend the game. I'm digging it so far and looking forward to playing more.
