1 - yes, it still caters to casuals and children, almost more so than people who have been gaming their whole lives.
2 - A PS4 or XBONE are in the $200-300 range, a proper gaming rig will cost you at least $900(and can go higher than $2k) or so. Depends on if you're building or buying.
3 - Some of the best games around are exclusively on consoles.
4 - just isnt anywhere near as powerful as the competition, and that is a negative regardless of how their fanboys want to spin it. There are PS3 games that look and run infinitely better than what i've seen so far on the switch.
5 - fuck handheld gaming
The wii was the last nintendo console i purchased. I played wii sports a few times and boxed that shit back up. Then i picked up Super Mario Galaxy, beat the game and that shit went back in its box and has been sitting in my closet ever since. I owned every Nintendo console that came out before the wii, and never touched anything with a Nintendo logo on it afterwards. The way i look at it is they turned their backs on their true fans with the wii by throwing us under the rug and reached to the whole smart phone crowd with all the elementary garbage they embraced with that console. They went from being the most respected name amongst the true gamers, to basically being the laughingstock of the industry. sad.
mark my words, that shit is going to fall harder than the wiiU did.
