I'm not sure if this is how they see it, but Project E would make it too easy to get materials, and magical crops would make it also too easy to farm materials. You'd lose interest very fast with how fast you get stuff, so the mods arent included to make you work more. That's just my opinion tho
After considering this for a bit, we've decided that ProjectE and magical crops would make it too easy to get all the items in the game, so we're going to DENY this suggestion
