My dad got me into video games when I was 4, and that was back in "communist" (socialist) Russia, in the institute of applied sciences of the academy of the ussr. We played Space Quest together, trying to solve puzzles. I was four, and I did not speak a single word of English back then.
Hadn't played games with mi padre ever since before 1996, that is UNTIL the Wii came out... I recall giving him the GameCube controller to enjoy a quiet game (quiet is a bit of a sarcastic term here) of WarioWare and him being very happy that he could easily remember where the A button was. Attempts to get him into Smash Bros. and MarioParty were met with disdain since he didn't feel like getting aquainted with the controller - something that I've noticed to be a universal fear in adults.
He was skeptical of the remote, though I've briefed him quite a bit on the nature of Wii one time over an hour-long drive to Houston one day, and he thought that the remote idea was "great in theory." (This was before the Wii was out). He picked it up with obvious dissapointment, that there were buttons on it, the names for which he always has troubles remembering. Usually, he gives a game a try, laughs and says "well, that's cool" and goes back to drinking tea, beer, wine, coffee, and scribbling his damn formulas.
We played Tennis for a little bit, but asking him if he wants to play it again, he said "yeah, I'll kick your ass this time." I've not heard my dad threated to kick my ass ever since I stopped making Cs in 9th grade. Even mom expressed her interest to "try it when you don't have all your friends watching me."
That said, both of my parents are long-time gamers, though very much of recreational and "puzzle" oriented variety (something that I guess is genetic). Sure, they don't pwn zombies in Zelda, but they also been relying to computer games as their way to have fun ever since I remember myself. Most of the titles are rather obscure, and an amazing variety of those games are Russian, or really weird european stuff, so I guess it isn't -that- much of a surprise that they "felt" the Wii controller. However, it is a joy to see them instantly understand how things are controlled, and upon closer inspection both have expressed the need to have a 'more serious' one-to-one relationship between the motion in the physical world and the game. In other words, both of my parental figures went from "wtf?" to "l33t gamerz" in a matter of 5 minute round of a Wii Sport of their choice.
That, and my dad thought his Mii looked cooler than mine because his has a "bitching mustache." Coming from a quantum optics PhD, it is a fact.
