The studio that makes those games, makes the best in their genre and is somehow punching above their weight. I got Elderborn too after playing Postal Brain Damaged and was impressed.
Everybody likes different genres, and this one probably wouldn't be mine, but it was entrancing and I basically immediately poured all my free time into it too. Totally worth the buy.
These days I'm more of a boomer shooter dude, but the trailer hooked me and I regret nothing. Haven't tried the newest Postal yet. Played postal 2 back in the day. blood west is likely next up for me.
Devs like Hyperstrange and New Blood are killing it these days, in a time when the big devs are laying off entire teams. It's amazing what happens when you have smaller devs who are focused on the games and not chasing number-go-up.
