I recently "stuck my head in the door" with 7DTD again, been about a year or so.
I can definitely see an improvement in game performance and appearance (on most things). That's reassuring from an old adopter's PoV.
While I can see some of the OP's points, I just decided to put the game down for long periods of time until they get into Beta. Too many iterations to fool with for me. It probably makes me a throwback player as I am not up-to-speed on 7DTD gameflow, etc. Anybody who's been around since early days knows the Devs are going to do it the way they want, like it or not. So I just decided to wait them out and see what the Beta holds in store.
The price I paid many years ago wasn't very expensive, so I don't hold a grudge against TFPs for failing to meet personal wants in 7DTD. I will reevaluate it when the time comes.
Kind of reminds me of Raphael's recent The Long Dark announcement to move to (mostly) paid content in the future. Some folks were quite upset, but my initial investment has gone on long enough and if it means me ponying up a few dollars to enjoy new content, so be it.
