My dad used to be a PC gamer back when the whole idea was on the rise in the early nineties. He was mostly into the EA Sports series for PC, particularly NHL. He even bought a Sidewinder pad (which I still have) to enhance his experience. When my parents gave me my N64 for my birthday as a little kid, my dad was enthusiastic about it. He even took me to the mall to buy Star Wars: Rogue Squadron the month it came out, and we played it all day long, and he was ten times more hyped about it than I was. Since his promotion, he hasn't had a lot of time for himself, and he stopped gaming. He's getting a bit interested in Halo 3, though, and he did enjoy Doom 3 when it came out after his friend gave a PC to him with the game.
Now I wish either of my parents would play ANY games, let alone Pokémon. Man, having my parents play Pokémon would open up ten whole years worth of understanding with how much fun it is to raise your own Pokémon and take on the gym leaders and Pokémon League with your own team which you grew and trained all on your own. I'd embrace the whole concept. For the longest time, they thought it was strictly for kids (mostly because of the anime, until I introduced them to the Japanese version of Mewtwo Strikes Back) until they saw that my group of friends and I still play the game. Since the classic days of Pokémon, they've accepted it as a part of their life, but they don't take much interest in it, and I can completely understand it. Sometimes though, I just wish they'd ask a question like "You catch that Latias yet, son?"
Oh well.
