I LIVE in the BOONDOCKS.
I use Verizon wireless 4G for my home internet. Its my only option other than satellite.
Their 4G coverage is pretty good in the areas I travel/camp. We take our internet with us when we camp.
I use a Cradlepoint router and verizon USB modem.
The 4G modems are usually backwards compatible to 3G, and Verizon was offering a reduced rate to switch to 4G. I saved $10/month by switching from 3 to 4.
About your online gaming. I think you may be unpleasantly surprised when you get the first bill because you went over your 5 Gig usage. You can upgrade to 10 Gig, but its costly.
I had to upgrade to 10 gig and we do not game or watch movies and were constantly going over 5 gig. You will be very surprised at how much data you use in a month. Every web site is loaded with content. For example: go to yahoo and mouse-over an ad. A video pops up and its playing before you can stop it.
My wife loves FB and Pin which are loaded with pictures.
Some providers are advertising unlimited data but they have poor coverage footprint and lacking on the data pipe servicing the backbone on their towers.
Although I haven't read their usage policy, I would be willing to bet they have a "fair use policy" which can/will slow your data speeds down to a crawl if you start gobbling up data watching your favorite show.
My opinion.
Unless the government steps in, I doubt we will see any unlimited cellular data plans that are worthwhile.
