Hey welcome to the forum. I haven't been on a lot recently because of life. I don't know your specifics or needs or plans but I have vehicle get home bags which are tiny and very light weight compared to my bug out bags. I am bugging in so if I have to bug out I want to be better prepared because I don't have much of a plan. My bug out bags are Army issue for durability so that right there is going to tell you they are heavy and they are full.
A lot of the guys suggested a pot but I want to specify. I spent 16 years in the military and I can tell you the Army mess kit that they withdrawn from service sucked ###. Years ago I bought some lots of East German mess kits and they are awesome. They are basically are all the same as this:

I like it, it is in all of our bug out bags. It is not just an eating utensil it is a pot that you can boil water in. It is well worth the weight and space.
This is also a really good deal:

Your water: In my opinion Lifestraw sucks. Every time you bend over at a water source you are allowing an enemy force to move on you. Unless you have an observer. I like Sawyer because you have options. You can backflow it to clean it from dirt. You can use it like a Lifestraw and better yet you can use the filter with the enclosed bag and take it with you. You can squeeze the water filling a clean container with clean water and take it with you. You can drink standing up while you look around providing security. Sawyer just has better options. I do have Lifestraw bottles. I got them on clearance and its a sports bottle with the Lifestraw filter inside.
Your going to be hungry and need the nutrients and energy. Add some mountain house meals to your pack. They are freeze dried and have little weight. Your kid(s) and your belly will be thankful.
If you have kids you need better crap than the Mylar survival blankets. Don't get rig of it but add a real sleeping bag or two. One for each member minus one or two. Why because you need to have at least one person on guard duty at all times. While a person is on guard duty they don't need a sleeping bag. So this allows less weight and space. This will actually allow more food to be carried. Have at least one real tent that is subdued colored. People under estimate the protection that a tent gives you. If you have kids then this is mandatory especially with a Mylar blanket plan.
If you have tools that require batteries then have spares. I suggest that you have rechargeable batteries and then have a lightweight solar panel to recharge the batteries. I have Goal Zero Nomad 7 with the battery charger. Today I don't recommend Goal Zero because the price sucks and there are cheaper alternatives. Something else the Solar chargers are good for is charging phones and tablets. Not so you can call someone but so you can upload information onto them such as PDF Books.
Something every bag needs is a survival book for the simple fact that you forget. In a crisis you have trouble remembering details so a hard copy of the Army Survival manual is a must. Personally I have the SAS Survival Guide in all of the BOB except one which is the Army manual.
If bags get to heavy then make alternative plans. Use a bike or bike/trailer. A cart or wagon and a very large baby stroller offers an option. Use your imagination.
Good luck
as for games, I'll probably work on a pi rassberry that plays ROM's for long battery life, but good thinking since my boys a 8 & 1
