Ahh, I think there's a few of us playing it. I've put like 22 hours into it so far.
It's great dude, it's somewhat primitive in terms of graphics and the lack of voice acting but it's charming as hell. The resolution is solid though, it takes advantage of the headset and everything is crisp and runs at a solid 90fps.
The gameplay/combat is great, the quests keep me curious about the story. Some people say there's no story but I'd say there is. It's kind of like a Souls game without all the lore. Just main quests and side quests that are kind of cryptic but not overly confusing. Basically go here and kill this, or find such and such item and bring it back to the quest giver. The dungeons are quite large, the sandbox hubworld is large enough too. There's rope climbing sections and no fall damage, taking a plunge down a hole that was like 300 feet high was so damn cool. Made me want to climb back up and do it again, lol.
Menu navigation and UI is confusing as hell at first but it's fine once you get the hang of it. You can craft weapons, potions, etc.
The combat, coop, and overall vibe is what makes it a total gem. It's just damn fun. If you like Souls games and Diablo 1/2, you really can't go wrong.
Please be careful with your surroundings though. This game will have your swinging your arms like crazy and you will do some massive damage to whatever you come in contact with in your house, lol.
If you get it and find yourself really confused by the UI, etc. just shoot me a message and we can link up in coop and I'll explain things to you.
