Projectors even come in 4K now. They are wicked fun outside. Drop in to your local Home Depot, grab a big white tarp, string it up on the side of the house or between a few trees. Run all the appropriate wires, hook up some decent sound and just have a great night with friends and family. We do it here, weather permitting, with movies instead of games but the same principles apply. I have a acre big side yard and all the neighbors from around my area come and we watch a good fun movie, have some beverages, pop a bunch of popcorn and let the kids run wild. You could do the same thing with some 100 inch plus gaming, depending on what you want to put out on a projector.
i bought a used ps3 a couple of years ago and its still my main gaming system for the few times in the week i do play, now i mainly read books on my kindle. the only things for me that were a must was a mic for online play, and a charging dock for my controller so i dont have to deal with a bunch of cables and i just put it back on the dock when im done playing. for the first 2 weeks or so i used the cable that came with it and a 6 ft usb extension i bought off of monoprice really cheap
sweet, the extensions i have are still running strong and monoprice is amazing for cheap good quality various cords and cables. i have them running from the usb ports on the back of my pc to my desk and they show no signs of fraying or a loose connector. i also bought one of their cheap 50 ft. ethernet cable to run under the house to my bedroom since the house wasnt wired with ethenet ports and its been great for over 5 years now.
