How.... ?
Errrr.... uhhhhhh..... does not at all count for an answer?
I've been playing video games for almost two decades now, and I haven't noted much change.
Let's see here.
At about 6-7 years old, I liked Pac-Man, Atari Circus, Super Mario Bros., Adventures of Lolo, and Kirby's Adventure.
At about 9-11, I liked The Legend of Zelda: A Link to the Past, Super Mario World, and Final Fantasy "II". Oh, and Sonic the Hedgehog, Disney's Magical Quest, and some other Super NES games that surely existed at that time.
At about 12-14, I liked Chrono Trigger, Super Mario RPG, and all the other later SNES video games. And Final Fantasy VII, Nights into Dreams... so many things.
At about 14-16, I liked Final Fantasy X, Kingdom Hearts, and ummmmmmmmmmmmmmmmmmmmmmmmm, lots of games.
At about 18-22, I didn't play many video games. I decided to cut everything "geeky" out of my life, like video games and anime, I only listened to Jpop and studied Japanese. As well as tried everything possible outside of that to be "normal" and "cool" and was fairly ashamed to have once watched anime or played video games. That didn't work out too well and everyone on the internet hated my guts. Not that things are much better now...
24-now, I like Touhou, Tales of Symphonia, Tales of the Abyss, Tales of anything, Disgaea, Shin Megami anything, pretty much anything moe otaku related.
Nope, I'm pretty much the same person. Though I do seem to play more STGs now than I used to. I played and like them back then, one of the few PC games I was able to afford was Desert Storm. But still.
