My main issue with 7dtd and most survival games in general is its far to easy to get established and self sufficent, once you get to this point the game loses most of its meaning. Especally in 7dtd, where you can almost always craft better tools than you'll find later on. The game needs more loot only gear, mods are a good start, but i'd like new weapons, legendary ver of current weapons and armor that are all loot only, not avail on trader or craftable, to give the player a reason to go out and explore. Just surviving in 7dtd once established bores me, and I tend to start a new game by this point. It can/will get better as it is alpha.
