I for one would love to have more slots in the backpack (there was a discussion for a while on that) and some new foods, items, War of the Walkers is a great mod that has a lot of good new foods, items, but the problem I see in that it a lot of the recipes need meat and that is very hard to find, bear stew, rabbit stew are just a couple I remember, but I hardly ever see game while watching some play it, and they are out and about traveling, but very little game shows up. Without that food they find, I think they would probably be starving all the time.There is a lot of great loot, but I think a bit too much. I would love to see it be the middle area of what is in the game and what that mod game has. Especially that zombies who are hard to kill finally have something worthwhile spending the time killing them instead of the nothing that they have now.
The POIs, those are just awesome, and it would be great if the fun pimps could get with the developers of that mod and buy some of their work, but I don't know enough of how it would affect the game long term, interact with what is in the game and will be added to the game.
I admit to the wondering of if it works in a mod, why can't it work in the game but know it isn't as simple as it seems, maybe? I don't know and I am willing to go there has to be a good reason for it not being added, besides the most important that it isn't part of the kickstarter list and so is set aside for later review.
Right now, on why we haven't seen anything, I am going that whatever was planned by MM to show us, there was a problem, you don't want to show a problem and so it has been delayed. Why not tell us it is delayed, there is a problem? Busy, trying to find the problem, the answer to it and at the same time get the other work that is falling behind because of the problem they are working on finding and fixing.
It isn't as simple as it seems, we are on the outside looking in see the nice view of the display room, while they are in the back with the wires, thingamabobs, whatchamacallits, and whateveryit is all over the place. I think of it as a place that someone opened a couple of jigsaw puzzle boxes that have 1000 pieces and tossed them all over the room and they are trying to find the pieces and put them in the correct box.
Use your imagination and picture them in a room full of equipment and looking for those physical puzzle pieces and then see them as the ones inside the programing and realize it can be a huge, royal pain in the a double s to find and fix, give them some time.
