There is another time limit, but there are ways around that as well. The 1.1 Patch removes the second time limit. Part of the game is questing to find the water-chip. My stats are changing. Some armor can increase your Strength.
Inventory is annoying.
Use the method you feel most comfortable with. To move many items into a container, move the container to one of your hands, and drag items to it while in inventory, then move the filled container back into the inventory list. You can arm dynamite and drop it from within Inventory. You can use items on an NPC to give it to him or you can use Barter but the best way is to Steal from them. When you Steal from them, they will not care what items you give or take.
